Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Large changes to the Win32 backend, partially made necessary by the 2000-05-02 Tor Lillqvist <tml@iki.fi> Large changes to the Win32 backend, partially made necessary by the changes to the backend-independent internal structures. Attempts to implement similar backing store stuff as on X11. The current (CVS) version of the Win32 backend is *not* as stable as it was before the no-flicker branch was merged. A zipfile with that version is available from http://www.gimp.org/win32/. That should be use by "production" code until this CVS version is usable. (But note, the Win32 backend has never been claimed to be "production quality".) * README.win32: Add the above comment about versions. * gdk/gdkwindow.c: Don't use backing store for now on Win32. * gdk/gdk.def: Update. * gdk/gdkfont.h: Declare temporary Win32-only functions. Will presumably be replaced by some more better mechanism as 1.4 gets closer to release shape. * gdk/makefile.{cygwin,msc}: Update. * gdk/win32/*.c: Correct inclusions of the backend-specific and internal headers. Change code according to changes in these. Use gdk_drawable_*, not gdk_window_* where necessary. * gdk/win32/gdkdnd-win32.c: Use MISC selector for GDK_NOTE, not our old DND. * gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_text): Don't try to interpret single characters as UTF-8. Thanks to Hans Breuer. Use correct function name in warning messages. * gdk/win32/gdkevents-win32.c: Use correct parameter lists for the GSourceFuncs gdk_event_prepare and gdk_event_check. (gdk_event_get_graphics_expose): Do implement, use PeekMessage. Thanks to Hans Breuer. (event_mask_string): Debugging function to print an GdkEventMask. (gdk_pointer_grab): Use it. * gdk/win32/gdkfont-win32.c: The Unicode subrange that the (old) book I used claimed was Hangul actually is CJK Unified Ideographs Extension A. Also, Hangul Syllables were missing. Improve logging. * gdk/win32/gdkgc-win32.c: Largish changes. * gdk/win32/gdkim-win32.c (gdk_set_locale): Use g_win32_getlocale() from GLib, and not setlocale() to get current locale name. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkwin32.h: Move stuff from gdkprivate-win32.h to gdkwin32.h, similarily as in the X11 backend. * gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Bugfix, assignment was used instead of equals in if test. Thanks to Hans Breuer. * gdk/win32/makefile.{cygwin,msc} * gtk/makefile.{cygwin,msc}: Updates. Better kludge to get the path to the Win32 headers that works also with the mingw compiler. * gtk/gtkstyle.c: Include <string.h>.

Merge from stable: 2002-12-09 Tor Lillqvist <tml@iki.fi> Merge from stable: * gdk/win32/gdkdrawable-win32.c (generic_draw): Don't leak stipple_gc. More checks for errors. Use correct ternary ROP when blitting the foreground into the tile pixmap onto those pixels where the stipple is set. (I didn't notice that I had used the wrong one, as it didn't matter on Win2k, where DIB sections apparently are zeroed upon creation. But on Win98 they have random initial contents. Thanks to Hans Breuer for reporting this.) (gdk_win32_draw_rectangle, gdk_win32_draw_arc, gdk_win32_draw_polygon): Don't pass the LINE_ATTRIBUTES bits to generic_draw() if drawing a filled figure. * gdk/win32/gdkmain-win32.c (_gdk_win32_print_dc): Minor cosmetics. (_gdk_win32_gcvalues_mask_to_string): Initialize buffer as empty. (_gdk_win32_window_state_to_string): New debugging output helper function. * gdk/win32/gdkevents-win32.c: Minor debugging output changes. (gdk_event_translate): Ignore the WM_SHOWWINDOW/SW_OTHERUNZOOM or SW_OTHERZOOM messages. Do not generate a GDK_UNMAP event for WM_SIZE/SIZE_MINIMIZED messages, they do not really corrspond to unmapping on X11. Set window state correctly for all three of SIZE_{MINIMIZED,MAXIMIZED,RESTORED}. A maximized and then iconified ("minimized" in Windows terminology) window still has the "maximized" property, i.e. when deiconified, it will reappear as maximized. (#10557) * gdk/win32/gdkprivate-win32.h: Declare new function. (WIN32_API_FAILED, WIN32_GDI_FAILED, OTHER_API_FAILED): Don't use __PRETTY_FUNCTION__ if __GNUC__ >= 3, to avoid warning message. * gdk/win32/gdkwindow-win32.c (show_window_internal): Handle more situations. Add parameter to tell whether deiconifying. Code reorg: Return early when appropriate instead of using nested if statements. If just deiconifying without raising, restore active window. (#10557) (gdk_window_hide, gdk_window_withdraw, gdk_window_iconify, gdk_window_deiconify, gdk_window_maximize, gdk_window_unmaximize, gdk_window_focus): Use _gdk_win32_window_state_to_string() in debugging output. (gdk_window_iconify): Restore active window after calling ShowWindow(). Otherwise the "next" window gets activated. (gdk_window_stick, gdk_window_unstick): Don't output any warnings. (gdk_window_set_transient_for): Rewrite. Just call SetWindowLong() with GWL_HWNDPARENT, which despite its name sets the *owner* window, which should be exactly what we want. The PSDK documentation is said to be misleading. testgtk's modal window test now works much better. (#50586)

Merge from stable: 2002-11-24 Tor Lillqvist <tml@iki.fi> Merge from stable: Implement tiles and stipples for all drawing methids (except the deprecated draw_text() and draw_text_wc()). * gdk/win32/gdkdrawable-win32.c: Remove the already ifdeffed-out code that didn't use generic_draw(). (generic_draw): When drawing into the mask (for tiled/stippled fill styles), copy the line attributes from the actual GC. Also ask for text drawing setup if needed.

(draw_lines, gdk_win32_draw_lines, draw_polygon, gdk_win32_draw_polygon, draw_segments, gdk_win32_draw_segments, draw_arc, gdk_win32_draw_arc): Use generic_draw(), thus implementing tiled and stippled fill styles for lines, polygons, segments, and args. (gdk_win32_draw_points): Use Rectangle() instead of SetPixel(). Rectangle() uses the function (raster op) set for the HDC, SetPixel() doesn't. (widen_bounds): New function, refactoring. * gdk/win32/gdkgc-win32.c: Remove ifdeffed-out code. (predraw_set_foreground, gdk_win32_hdc_get): Some code moved around. Call SetROP2() only if necessary. Call SetTextColor() only if GDK_GC_FOREGROUND flag present. Don't handle GDK_OPAQUE_STIPPLED here, has been superseded by the code in generic_draw(). Always create a solid brush. Remove background color handling from here. The background color of a GdkGC is supposed to affect only GDK_OPAQUE_STIPPLED fill style, which it is already handled in generic_draw(), and GDK_LINE_DOUBLE_DASH lines, which aren't implemented properly anyway. Calling SetBkColor() is unnecessary as we always use TRANSPARENT text output.

#define LINE_ATTRIBUTES (GDK_GC_LINE_WIDTH|GDK_GC_LINE_STYLE| \
GDK_GC_CAP_STYLE|GDK_GC_JOIN_STYLE)
Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING.

Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style).

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed.

Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions.

Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 2002-11-12 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/*.c: Rename all global variables and functions to start with underscore. Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite.

(blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought.

Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable. Don't attempt any compression of configure or expose events here, handled elsewhere. (erase_background): Accumulate window offsets when traversing up the parent chain for GDK_PARENT_RELATIVE_BG, in order to get correct alignment of background pixmaps. Don't fill with BLACK_BRUSH if GDK_NO_BG. (gdk_event_get_graphics_expose): A bit more verbose debugging output. (gdk_event_translate): Use _gdk_win32_get_next_tick().

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 2002-11-12 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/*.c: Rename all global variables and functions to start with underscore. Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite. Make static. Must take tile origin parameters, too. (gdk_win32_draw_rectangle): Pass the tile/stipple origin to _gdk_win32_draw_tiles(). Remove #if 0 code. (blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought. A simple call to BitBlt() is enough. * gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused latin_locale_loaded variable. (_gdk_win32_get_next_tick): New function. Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable.

(_gdk_win3_gdkregion_to_hrgn): New function, code snippet extracted from gdk_win32_hdc_get(). * gdk/win32/gdkgeometry-win32.c: Ifdef out the translate_queue handling. (gdk_window_copy_area_scroll): Increase clipRect to avoid ScrollWindowEx() not scrolling pixels it thinks are invalid. Scroll also children with the ScrollWindowEx() call. No need to call gdk_window_move() on the children. (gdk_window_scroll): Don't do guffaw scrolling. (gdk_window_compute_position): Fix typo, used win32_y where x was intended. (gdk_window_premove, gdk_window_postmove, gdk_window_clip_changed): Add debugging output. (_gdk_windowing_window_queue_antiexpose): Just call ValidateRgn() on the region.

(_gdk_windowing_window_init, gdk_window_foreign_new): Call _gdk_window_init_position() like in the X11 backend. (gdk_window_reparent): Don't call the now nonexistent gdk_window_set_static_win_gravity(). No idea what should be done instead. (gdk_window_get_geometry): The returned x and y should be relative to parent. Used to be always zero.. (gdk_window_set_static_gravities): Return FALSE if trying to set static gravity. * gdk/win32/gdkprivate-win32.h: Drop the clip_region field from GdkGCWin32. Only use the HRGN hcliprgn.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 2002-11-12 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/*.c: Rename all global variables and functions to start with underscore. Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite. Make static. Must take tile origin parameters, too. (gdk_win32_draw_rectangle): Pass the tile/stipple origin to _gdk_win32_draw_tiles(). Remove #if 0 code. (blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought. A simple call to BitBlt() is enough. * gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused latin_locale_loaded variable. (_gdk_win32_get_next_tick): New function. Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable. Don't attempt any compression of configure or expose events here, handled elsewhere. (erase_background): Accumulate window offsets when traversing up the parent chain for GDK_PARENT_RELATIVE_BG, in order to get correct alignment of background pixmaps. Don't fill with BLACK_BRUSH if GDK_NO_BG. (gdk_event_get_graphics_expose): A bit more verbose debugging output. (gdk_event_translate): Use _gdk_win32_get_next_tick(). In the WM_PAINT handler, don't check for empty update rect. When we get a WM_PAINT, the update region isn't empty. And if it for some strange reason is, that will be handled later anyway. Call GetUpdateRgn() before calling BeginPaint() and EndPaint() (which empty the update region). * gdk/win32/gdkdnd-win32.c * gdk/win32/gdkinput-win32.c: Use _gdk_win32_get_next_tick(). * gdk/win32/gdkfont-win32.c: Use %p to print HFONTs.

Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed.

Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping.

Merge from stable: 2002-11-24 Tor Lillqvist <tml@iki.fi> Merge from stable: Implement tiles and stipples for all drawing methids (except the deprecated draw_text() and draw_text_wc()). * gdk/win32/gdkdrawable-win32.c: Remove the already ifdeffed-out code that didn't use generic_draw(). (generic_draw): When drawing into the mask (for tiled/stippled fill styles), copy the line attributes from the actual GC. Also ask for text drawing setup if needed. Use differently set up HDCs in the normal and tiled/stippled cases. (draw_lines, gdk_win32_draw_lines, draw_polygon, gdk_win32_draw_polygon, draw_segments, gdk_win32_draw_segments, draw_arc, gdk_win32_draw_arc): Use generic_draw(), thus implementing tiled and stippled fill styles for lines, polygons, segments, and args. (gdk_win32_draw_points): Use Rectangle() instead of SetPixel(). Rectangle() uses the function (raster op) set for the HDC, SetPixel() doesn't. (widen_bounds): New function, refactoring. * gdk/win32/gdkgc-win32.c: Remove ifdeffed-out code. (predraw_set_foreground, gdk_win32_hdc_get): Some code moved around. Call SetROP2() only if necessary. Call SetTextColor() only if GDK_GC_FOREGROUND flag present. Don't handle GDK_OPAQUE_STIPPLED here, has been superseded by the code in generic_draw(). Always create a solid brush. Remove background color handling from here. The background color of a GdkGC is supposed to affect only GDK_OPAQUE_STIPPLED fill style, which it is already handled in generic_draw(), and GDK_LINE_DOUBLE_DASH lines, which aren't implemented properly anyway. Calling SetBkColor() is unnecessary as we always use TRANSPARENT text output. (gdk_win32_hdc_get, gdk_win32_hdc_release): Add doc comments, as these are public functions. * gdk/win32/gdkevents-win32.c (synthesize_expose_events): Don't synthesize expose events for GDK_INPUT_ONLY windows. (gdk_event_translate): On WM_SIZE, call gdk_synthesize_window_state() if window was iconified, restored or maximized. (#98983, Arnaud Charlet) * gtk+/gdk/win32/gdkwindow-win32.c (gdk_window_get_frame_extents): Fix typo in setting y. (#98983, Arnaud Charlet)

Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option.

(predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that.

Set window state correctly for all three of SIZE_{MINIMIZED,MAXIMIZED,RESTORED}.

Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x.

I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed.

Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap.

Merge from stable: 2002-12-09 Tor Lillqvist <tml@iki.fi> Merge from stable: * gdk/win32/gdkdrawable-win32.c (generic_draw): Don't leak stipple_gc. More checks for errors. Use correct ternary ROP when blitting the foreground into the tile pixmap onto those pixels where the stipple is set. (I didn't notice that I had used the wrong one, as it didn't matter on Win2k, where DIB sections apparently are zeroed upon creation. But on Win98 they have random initial contents. Thanks to Hans Breuer for reporting this.) (gdk_win32_draw_rectangle, gdk_win32_draw_arc, gdk_win32_draw_polygon): Don't pass the LINE_ATTRIBUTES bits to generic_draw() if drawing a filled figure. * gdk/win32/gdkmain-win32.c (_gdk_win32_print_dc): Minor cosmetics. (_gdk_win32_gcvalues_mask_to_string): Initialize buffer as empty. (_gdk_win32_window_state_to_string): New debugging output helper function. * gdk/win32/gdkevents-win32.c: Minor debugging output changes. (gdk_event_translate): Ignore the WM_SHOWWINDOW/SW_OTHERUNZOOM or SW_OTHERZOOM messages. Do not generate a GDK_UNMAP event for WM_SIZE/SIZE_MINIMIZED messages, they do not really corrspond to unmapping on X11. Set window state correctly for all three of SIZE_{MINIMIZED,MAXIMIZED,RESTORED}. A maximized and then iconified ("minimized" in Windows terminology) window still has the "maximized" property, i.e. when deiconified, it will reappear as maximized. (#10557) * gdk/win32/gdkprivate-win32.h: Declare new function. (WIN32_API_FAILED, WIN32_GDI_FAILED, OTHER_API_FAILED): Don't use __PRETTY_FUNCTION__ if __GNUC__ >= 3, to avoid warning message. * gdk/win32/gdkwindow-win32.c (show_window_internal): Handle more situations. Add parameter to tell whether deiconifying. Code reorg: Return early when appropriate instead of using nested if statements. If just deiconifying without raising, restore active window. (#10557) (gdk_window_hide, gdk_window_withdraw, gdk_window_iconify, gdk_window_deiconify, gdk_window_maximize, gdk_window_unmaximize, gdk_window_focus): Use _gdk_win32_window_state_to_string() in debugging output. (gdk_window_iconify): Restore active window after calling ShowWindow(). Otherwise the "next" window gets activated. (gdk_window_stick, gdk_window_unstick): Don't output any warnings. (gdk_window_set_transient_for): Rewrite. Just call SetWindowLong() with GWL_HWNDPARENT, which despite its name sets the *owner* window, which should be exactly what we want. The PSDK documentation is said to be misleading. testgtk's modal window test now works much better. (#50586)

Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping.

(draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years.

(gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that.

Merge from stable: 2002-11-24 Tor Lillqvist <tml@iki.fi> Merge from stable: Implement tiles and stipples for all drawing methids (except the deprecated draw_text() and draw_text_wc()). * gdk/win32/gdkdrawable-win32.c: Remove the already ifdeffed-out code that didn't use generic_draw(). (generic_draw): When drawing into the mask (for tiled/stippled fill styles), copy the line attributes from the actual GC. Also ask for text drawing setup if needed. Use differently set up HDCs in the normal and tiled/stippled cases. (draw_lines, gdk_win32_draw_lines, draw_polygon, gdk_win32_draw_polygon, draw_segments, gdk_win32_draw_segments, draw_arc, gdk_win32_draw_arc): Use generic_draw(), thus implementing tiled and stippled fill styles for lines, polygons, segments, and args. (gdk_win32_draw_points): Use Rectangle() instead of SetPixel(). Rectangle() uses the function (raster op) set for the HDC, SetPixel() doesn't. (widen_bounds): New function, refactoring. * gdk/win32/gdkgc-win32.c: Remove ifdeffed-out code. (predraw_set_foreground, gdk_win32_hdc_get): Some code moved around. Call SetROP2() only if necessary. Call SetTextColor() only if GDK_GC_FOREGROUND flag present. Don't handle GDK_OPAQUE_STIPPLED here, has been superseded by the code in generic_draw(). Always create a solid brush. Remove background color handling from here. The background color of a GdkGC is supposed to affect only GDK_OPAQUE_STIPPLED fill style, which it is already handled in generic_draw(), and GDK_LINE_DOUBLE_DASH lines, which aren't implemented properly anyway. Calling SetBkColor() is unnecessary as we always use TRANSPARENT text output. (gdk_win32_hdc_get, gdk_win32_hdc_release): Add doc comments, as these are public functions. * gdk/win32/gdkevents-win32.c (synthesize_expose_events): Don't synthesize expose events for GDK_INPUT_ONLY windows. (gdk_event_translate): On WM_SIZE, call gdk_synthesize_window_state() if window was iconified, restored or maximized. (#98983, Arnaud Charlet) * gtk+/gdk/win32/gdkwindow-win32.c (gdk_window_get_frame_extents): Fix typo in setting y. (#98983, Arnaud Charlet)

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

Merge from stable: 2002-11-24 Tor Lillqvist <tml@iki.fi> Merge from stable: Implement tiles and stipples for all drawing methids (except the deprecated draw_text() and draw_text_wc()). * gdk/win32/gdkdrawable-win32.c: Remove the already ifdeffed-out code that didn't use generic_draw().

(gdk_win32_draw_points): Use Rectangle() instead of SetPixel(). Rectangle() uses the function (raster op) set for the HDC, SetPixel() doesn't. (widen_bounds): New function, refactoring. * gdk/win32/gdkgc-win32.c: Remove ifdeffed-out code. (predraw_set_foreground, gdk_win32_hdc_get): Some code moved around. Call SetROP2() only if necessary. Call SetTextColor() only if GDK_GC_FOREGROUND flag present. Don't handle GDK_OPAQUE_STIPPLED here, has been superseded by the code in generic_draw(). Always create a solid brush. Remove background color handling from here. The background color of a GdkGC is supposed to affect only GDK_OPAQUE_STIPPLED fill style, which it is already handled in generic_draw(), and GDK_LINE_DOUBLE_DASH lines, which aren't implemented properly anyway. Calling SetBkColor() is unnecessary as we always use TRANSPARENT text output. (gdk_win32_hdc_get, gdk_win32_hdc_release): Add doc comments, as these are public functions. * gdk/win32/gdkevents-win32.c (synthesize_expose_events): Don't synthesize expose events for GDK_INPUT_ONLY windows.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that.

Merge from stable: 2002-12-09 Tor Lillqvist <tml@iki.fi> Merge from stable: * gdk/win32/gdkdrawable-win32.c (generic_draw): Don't leak stipple_gc. More checks for errors. Use correct ternary ROP when blitting the foreground into the tile pixmap onto those pixels where the stipple is set. (I didn't notice that I had used the wrong one, as it didn't matter on Win2k, where DIB sections apparently are zeroed upon creation. But on Win98 they have random initial contents. Thanks to Hans Breuer for reporting this.) (gdk_win32_draw_rectangle, gdk_win32_draw_arc, gdk_win32_draw_polygon): Don't pass the LINE_ATTRIBUTES bits to generic_draw() if drawing a filled figure. * gdk/win32/gdkmain-win32.c (_gdk_win32_print_dc): Minor cosmetics. (_gdk_win32_gcvalues_mask_to_string): Initialize buffer as empty. (_gdk_win32_window_state_to_string): New debugging output helper function. * gdk/win32/gdkevents-win32.c: Minor debugging output changes. (gdk_event_translate): Ignore the WM_SHOWWINDOW/SW_OTHERUNZOOM or SW_OTHERZOOM messages. Do not generate a GDK_UNMAP event for WM_SIZE/SIZE_MINIMIZED messages, they do not really corrspond to unmapping on X11. Set window state correctly for all three of SIZE_{MINIMIZED,MAXIMIZED,RESTORED}. A maximized and then iconified ("minimized" in Windows terminology) window still has the "maximized" property, i.e. when deiconified, it will reappear as maximized. (#10557) * gdk/win32/gdkprivate-win32.h: Declare new function. (WIN32_API_FAILED, WIN32_GDI_FAILED, OTHER_API_FAILED): Don't use __PRETTY_FUNCTION__ if __GNUC__ >= 3, to avoid warning message. * gdk/win32/gdkwindow-win32.c (show_window_internal): Handle more situations. Add parameter to tell whether deiconifying. Code reorg: Return early when appropriate instead of using nested if statements. If just deiconifying without raising, restore active window. (#10557) (gdk_window_hide, gdk_window_withdraw, gdk_window_iconify, gdk_window_deiconify, gdk_window_maximize, gdk_window_unmaximize, gdk_window_focus): Use _gdk_win32_window_state_to_string() in debugging output. (gdk_window_iconify): Restore active window after calling ShowWindow(). Otherwise the "next" window gets activated. (gdk_window_stick, gdk_window_unstick): Don't output any warnings. (gdk_window_set_transient_for): Rewrite. Just call SetWindowLong() with GWL_HWNDPARENT, which despite its name sets the *owner* window, which should be exactly what we want. The PSDK documentation is said to be misleading. testgtk's modal window test now works much better. (#50586)

Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite. Make static. Must take tile origin parameters, too. (gdk_win32_draw_rectangle): Pass the tile/stipple origin to _gdk_win32_draw_tiles(). Remove #if 0 code. (blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought. A simple call to BitBlt() is enough. * gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused latin_locale_loaded variable. (_gdk_win32_get_next_tick): New function. Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable. Don't attempt any compression of configure or expose events here, handled elsewhere. (erase_background): Accumulate window offsets when traversing up the parent chain for GDK_PARENT_RELATIVE_BG, in order to get correct alignment of background pixmaps. Don't fill with BLACK_BRUSH if GDK_NO_BG. (gdk_event_get_graphics_expose): A bit more verbose debugging output. (gdk_event_translate): Use _gdk_win32_get_next_tick(). In the WM_PAINT handler, don't check for empty update rect. When we get a WM_PAINT, the update region isn't empty. And if it for some strange reason is, that will be handled later anyway. Call GetUpdateRgn() before calling BeginPaint() and EndPaint() (which empty the update region). * gdk/win32/gdkdnd-win32.c * gdk/win32/gdkinput-win32.c: Use _gdk_win32_get_next_tick(). * gdk/win32/gdkfont-win32.c: Use %p to print HFONTs. (gdk_text_size): Remove, unused. * gdk/win32/gdkgc-win32.c: Set clip origins to zero when appropriate. (gdk_gc_copy): Increase refcount on colormap if present. (gdk_win32_hdc_get): Handle just hcliprgn. If we have a stipple, combine it with clip region after selecting into the DC. (_gdk_win32_bitmap_to_hrgn): Rename from _gdk_win32_bitmap_to_region. (_gdk_win3_gdkregion_to_hrgn): New function, code snippet extracted from gdk_win32_hdc_get(). * gdk/win32/gdkgeometry-win32.c: Ifdef out the translate_queue handling. (gdk_window_copy_area_scroll): Increase clipRect to avoid ScrollWindowEx() not scrolling pixels it thinks are invalid. Scroll also children with the ScrollWindowEx() call. No need to call gdk_window_move() on the children. (gdk_window_scroll): Don't do guffaw scrolling. (gdk_window_compute_position): Fix typo, used win32_y where x was intended. (gdk_window_premove, gdk_window_postmove, gdk_window_clip_changed): Add debugging output. (_gdk_windowing_window_queue_antiexpose): Just call ValidateRgn() on the region. (_gdk_window_process_expose): No use for the serial number parameter now. Instead of a rectangle, take a region parameter, as Windows gives us one in WM_PAINT. * gdk/win32/gdkmain-win32.c (_gdk_win32_lbstyle_to_string, _gdk_win32_pstype_to_string, _gdk_win32_psstyle_to_string, _gdk_win32_psendcap_to_string, _gdk_win32_psjoin_to_string, _gdk_win32_rect_to_string, _gdk_win32_gdkrectangle_to_string, _gdk_win32_gdkregion_to_string): New debugging functions. (static_printf): Helper function for the above. sprintfs into a static circular buffer, return value should be used "soon". * gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Plug memory leak, free list after use. (gdk_window_gravity_works): Remove, we know that there is no such thing on Windows. (gdk_window_set_static_bit_gravity, gdk_window_set_static_win_gravity): Ditto, remove, they didn't do anything anyway. (_gdk_windowing_window_init, gdk_window_foreign_new): Call _gdk_window_init_position() like in the X11 backend. (gdk_window_reparent): Don't call the now nonexistent gdk_window_set_static_win_gravity(). No idea what should be done instead. (gdk_window_get_geometry): The returned x and y should be relative to parent. Used to be always zero.. (gdk_window_set_static_gravities): Return FALSE if trying to set static gravity. * gdk/win32/gdkprivate-win32.h: Drop the clip_region field from GdkGCWin32. Only use the HRGN hcliprgn. Declare new functions. * gdk/win32/*.c: Use new debugging functions. * gdk/win32/rc/gdk.rc.in: Update copyright year.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 2002-11-12 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/*.c: Rename all global variables and functions to start with underscore. Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite. Make static. Must take tile origin parameters, too. (gdk_win32_draw_rectangle): Pass the tile/stipple origin to _gdk_win32_draw_tiles(). Remove #if 0 code. (blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought. A simple call to BitBlt() is enough. * gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused latin_locale_loaded variable. (_gdk_win32_get_next_tick): New function. Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable. Don't attempt any compression of configure or expose events here, handled elsewhere. (erase_background): Accumulate window offsets when traversing up the parent chain for GDK_PARENT_RELATIVE_BG, in order to get correct alignment of background pixmaps. Don't fill with BLACK_BRUSH if GDK_NO_BG. (gdk_event_get_graphics_expose): A bit more verbose debugging output. (gdk_event_translate): Use _gdk_win32_get_next_tick(). In the WM_PAINT handler, don't check for empty update rect. When we get a WM_PAINT, the update region isn't empty. And if it for some strange reason is, that will be handled later anyway. Call GetUpdateRgn() before calling BeginPaint() and EndPaint() (which empty the update region). * gdk/win32/gdkdnd-win32.c * gdk/win32/gdkinput-win32.c: Use _gdk_win32_get_next_tick(). * gdk/win32/gdkfont-win32.c: Use %p to print HFONTs. (gdk_text_size): Remove, unused. * gdk/win32/gdkgc-win32.c: Set clip origins to zero when appropriate. (gdk_gc_copy): Increase refcount on colormap if present. (gdk_win32_hdc_get): Handle just hcliprgn. If we have a stipple, combine it with clip region after selecting into the DC. (_gdk_win32_bitmap_to_hrgn): Rename from _gdk_win32_bitmap_to_region. (_gdk_win3_gdkregion_to_hrgn): New function, code snippet extracted from gdk_win32_hdc_get(). * gdk/win32/gdkgeometry-win32.c: Ifdef out the translate_queue handling. (gdk_window_copy_area_scroll): Increase clipRect to avoid ScrollWindowEx() not scrolling pixels it thinks are invalid. Scroll also children with the ScrollWindowEx() call. No need to call gdk_window_move() on the children. (gdk_window_scroll): Don't do guffaw scrolling. (gdk_window_compute_position): Fix typo, used win32_y where x was intended. (gdk_window_premove, gdk_window_postmove, gdk_window_clip_changed): Add debugging output. (_gdk_windowing_window_queue_antiexpose): Just call ValidateRgn() on the region. (_gdk_window_process_expose): No use for the serial number parameter now. Instead of a rectangle, take a region parameter, as Windows gives us one in WM_PAINT. * gdk/win32/gdkmain-win32.c (_gdk_win32_lbstyle_to_string, _gdk_win32_pstype_to_string, _gdk_win32_psstyle_to_string, _gdk_win32_psendcap_to_string, _gdk_win32_psjoin_to_string, _gdk_win32_rect_to_string, _gdk_win32_gdkrectangle_to_string, _gdk_win32_gdkregion_to_string): New debugging functions. (static_printf): Helper function for the above. sprintfs into a static circular buffer, return value should be used "soon". * gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Plug memory leak, free list after use. (gdk_window_gravity_works): Remove, we know that there is no such thing on Windows. (gdk_window_set_static_bit_gravity, gdk_window_set_static_win_gravity): Ditto, remove, they didn't do anything anyway. (_gdk_windowing_window_init, gdk_window_foreign_new): Call _gdk_window_init_position() like in the X11 backend. (gdk_window_reparent): Don't call the now nonexistent gdk_window_set_static_win_gravity(). No idea what should be done instead. (gdk_window_get_geometry): The returned x and y should be relative to parent. Used to be always zero.. (gdk_window_set_static_gravities): Return FALSE if trying to set static gravity. * gdk/win32/gdkprivate-win32.h: Drop the clip_region field from GdkGCWin32. Only use the HRGN hcliprgn. Declare new functions. * gdk/win32/*.c: Use new debugging functions. * gdk/win32/rc/gdk.rc.in: Update copyright year.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 2002-11-12 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/*.c: Rename all global variables and functions to start with underscore. Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed.

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite. Make static. Must take tile origin parameters, too. (gdk_win32_draw_rectangle): Pass the tile/stipple origin to _gdk_win32_draw_tiles(). Remove #if 0 code. (blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought. A simple call to BitBlt() is enough. * gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused latin_locale_loaded variable. (_gdk_win32_get_next_tick): New function. Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable. Don't attempt any compression of configure or expose events here, handled elsewhere. (erase_background): Accumulate window offsets when traversing up the parent chain for GDK_PARENT_RELATIVE_BG, in order to get correct alignment of background pixmaps. Don't fill with BLACK_BRUSH if GDK_NO_BG. (gdk_event_get_graphics_expose): A bit more verbose debugging output. (gdk_event_translate): Use _gdk_win32_get_next_tick(). In the WM_PAINT handler, don't check for empty update rect. When we get a WM_PAINT, the update region isn't empty. And if it for some strange reason is, that will be handled later anyway. Call GetUpdateRgn() before calling BeginPaint() and EndPaint() (which empty the update region). * gdk/win32/gdkdnd-win32.c * gdk/win32/gdkinput-win32.c: Use _gdk_win32_get_next_tick(). * gdk/win32/gdkfont-win32.c: Use %p to print HFONTs.

Improve and simplify line segment rendering on Win32, especially the 2005-06-23 Tor Lillqvist <tml@novell.com> Improve and simplify line segment rendering on Win32, especially the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

Fixes bug #306396. * gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's line_style, cap_style and join_style as such in the GdkGCWin32. Don't need to keep the pen_double_dash flag, we can check the line_style. * gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets up the GDI pen type, style, end cap and join attributes to use based on the pen width, GDK line style, end cap style, and join style. For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end cap style, which typically are used for XOR drawing where it is essential that the last pixel is not drawn, use a GDI cosmetic pen. Only for a cosmetic pen does GDI not draw the last pixel. I deduced this by experimetation, the documentation is rather vague. For other GDK pens use a geometric GDI pen. If the width is 0 or 1 and the GDK end cap style is GDK_CAP_BUTT, and the line style is GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also single-pixel length lines are drawn. (For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

(For sngle-pixel width lines roundness as such is of course irrelevant.) For dashed lines, use PS_ENDCAP_FLAT. For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE, respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING. For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to work better than PS_USERSTYLE. For other dashed lines, use PS_USERSTYLE and the dashes as set by the user (or the default four-pixel on-off style). (gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes): Call fixup_pen() to do the pen settings after modifying some of the GDK GC attributes that affect pens. * gdk/win32/gdkdrawable-win32.c (render_line_horizontal, render_line_vertical, draw_segments): Check GdkGCWin32::line_style instead of the the removed pen_double_dash member. Don't use PATCOPY unconditionally in the PatBlt() call, use a raster ope code that depends on the GC function in use. (draw_rectangle, draw_segments, draw_lines): Be more careful in deciding when to do the manual dash rendering. (draw_segments): Don't do any manual "last point" drawing at all. The above changes takes care of narrow line segments being drawn correctly in most cases, at least on NT-based Windows.

(generic_draw): When drawing into the mask (for tiled/stippled fill styles), copy the line attributes from the actual GC. Also ask for text drawing setup if needed. Use differently set up HDCs in the normal and tiled/stippled cases. (draw_lines, gdk_win32_draw_lines, draw_polygon, gdk_win32_draw_polygon, draw_segments, gdk_win32_draw_segments, draw_arc, gdk_win32_draw_arc): Use generic_draw(), thus implementing tiled and stippled fill styles for lines, polygons, segments, and args. (gdk_win32_draw_points): Use Rectangle() instead of SetPixel(). Rectangle() uses the function (raster op) set for the HDC, SetPixel() doesn't. (widen_bounds): New function, refactoring. * gdk/win32/gdkgc-win32.c: Remove ifdeffed-out code. (predraw_set_foreground, gdk_win32_hdc_get): Some code moved around. Call SetROP2() only if necessary. Call SetTextColor() only if GDK_GC_FOREGROUND flag present. Don't handle GDK_OPAQUE_STIPPLED here, has been superseded by the code in generic_draw(). Always create a solid brush. Remove background color handling from here. The background color of a GdkGC is supposed to affect only GDK_OPAQUE_STIPPLED fill style, which it is already handled in generic_draw(), and GDK_LINE_DOUBLE_DASH lines, which aren't implemented properly anyway. Calling SetBkColor() is unnecessary as we always use TRANSPARENT text output. (gdk_win32_hdc_get, gdk_win32_hdc_release): Add doc comments, as these are public functions. * gdk/win32/gdkevents-win32.c (synthesize_expose_events): Don't synthesize expose events for GDK_INPUT_ONLY windows. (gdk_event_translate): On WM_SIZE, call gdk_synthesize_window_state() if window was iconified, restored or maximized. (#98983, Arnaud Charlet) * gtk+/gdk/win32/gdkwindow-win32.c (gdk_window_get_frame_extents): Fix typo in setting y. (#98983, Arnaud Charlet)

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions.

For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to 2002-11-12 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/*.c: Rename all global variables and functions to start with underscore. Merge from stable: More work on the Win32 backend. The cause of some scrolling problems was that SetWindowPos() and ScrollWindowEx() don't blit those parts of the window they think are invalid. As we didn't keep Windows's update region in synch with GDK's, Windows thought those areas that in fact had been updated were invalid. Calling ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to be an elegant and efficient solution, removing from Windows's update region those areas we are about to repaint proactively. In some cases garbage leftover values were used for the clip origin in GdkGCWin32. This showed up as odd blank areas around the pixmaps included in the Text Widget in gtk-demo. Having the clip region either as a GdkRegion or a HRGN in GdkGCWin32 was unnecessary, it's better to just use a HRGN. The translation and antiexpose queue handling in gdkgeometry-win32.c seems unnecessary (and not implementable in the same way as on X11 anyway, no serial numbers) on Windows, ifdeffed out. Don't (try to) do guffaw scrolling as there is no static window gravity on Windows. Guffaw scrolling would be unnecessary anyway, as there is the ScrollWindow() API. This improves the behaviour of the Text Widget demo in gtk-demo a lot. But I have no idea how the lack of static win gravity should be handled in other places where the X11 code uses it. Especially _gdk_window_move_resize_child(). There is still some problem in expose handling. By moving an obscuring window back and forth over testgtk's main window, for instance, every now and then you typically get narrow vertical or horizontal strips of pixels that haven't been properly redrawn after being exposed. A fencepost error somewhere? Otherwise, all of testgtk and gtk-demo except "big windows" now seem to work pretty well. Bug #79720 should be fixed now. * gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string, gdk_win32_print_paletteentries, gdk_win32_print_system_palette, gdk_win32_print_hpalette) * gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description) * gdk/win32/gdkevents-win32.c (gdk_win32_message_name): Move all debugging helper functions to gdkmain-win32.c. * gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles): Rewrite. Make static. Must take tile origin parameters, too. (gdk_win32_draw_rectangle): Pass the tile/stipple origin to _gdk_win32_draw_tiles(). Remove #if 0 code. (blit_inside_window): Don't call ScrollDC(), that didn't work at all like I thought. A simple call to BitBlt() is enough. * gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused latin_locale_loaded variable. (_gdk_win32_get_next_tick): New function. Used to make sure timestamps of events are always increasing, both in events generated from the window procedure and in events gotten via PeekMessage(). Not sure whether this is actually useful, but it seemed as a good idea. (real_window_procedure): Don't use a local GdkEventPrivate variable. Don't attempt any compression of configure or expose events here, handled elsewhere. (erase_background): Accumulate window offsets when traversing up the parent chain for GDK_PARENT_RELATIVE_BG, in order to get correct alignment of background pixmaps. Don't fill with BLACK_BRUSH if GDK_NO_BG. (gdk_event_get_graphics_expose): A bit more verbose debugging output. (gdk_event_translate): Use _gdk_win32_get_next_tick(). In the WM_PAINT handler, don't check for empty update rect. When we get a WM_PAINT, the update region isn't empty. And if it for some strange reason is, that will be handled later anyway. Call GetUpdateRgn() before calling BeginPaint() and EndPaint() (which empty the update region). * gdk/win32/gdkdnd-win32.c * gdk/win32/gdkinput-win32.c: Use _gdk_win32_get_next_tick(). * gdk/win32/gdkfont-win32.c: Use %p to print HFONTs. (gdk_text_size): Remove, unused. * gdk/win32/gdkgc-win32.c: Set clip origins to zero when appropriate. (gdk_gc_copy): Increase refcount on colormap if present. (gdk_win32_hdc_get): Handle just hcliprgn. If we have a stipple, combine it with clip region after selecting into the DC. (_gdk_win32_bitmap_to_hrgn): Rename from _gdk_win32_bitmap_to_region. (_gdk_win3_gdkregion_to_hrgn): New function, code snippet extracted from gdk_win32_hdc_get(). * gdk/win32/gdkgeometry-win32.c: Ifdef out the translate_queue handling. (gdk_window_copy_area_scroll): Increase clipRect to avoid ScrollWindowEx() not scrolling pixels it thinks are invalid. Scroll also children with the ScrollWindowEx() call. No need to call gdk_window_move() on the children. (gdk_window_scroll): Don't do guffaw scrolling. (gdk_window_compute_position): Fix typo, used win32_y where x was intended. (gdk_window_premove, gdk_window_postmove, gdk_window_clip_changed): Add debugging output. (_gdk_windowing_window_queue_antiexpose): Just call ValidateRgn() on the region. (_gdk_window_process_expose): No use for the serial number parameter now. Instead of a rectangle, take a region parameter, as Windows gives us one in WM_PAINT. * gdk/win32/gdkmain-win32.c (_gdk_win32_lbstyle_to_string, _gdk_win32_pstype_to_string, _gdk_win32_psstyle_to_string, _gdk_win32_psendcap_to_string, _gdk_win32_psjoin_to_string, _gdk_win32_rect_to_string, _gdk_win32_gdkrectangle_to_string, _gdk_win32_gdkregion_to_string): New debugging functions. (static_printf): Helper function for the above. sprintfs into a static circular buffer, return value should be used "soon". * gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Plug memory leak, free list after use. (gdk_window_gravity_works): Remove, we know that there is no such thing on Windows. (gdk_window_set_static_bit_gravity, gdk_window_set_static_win_gravity): Ditto, remove, they didn't do anything anyway. (_gdk_windowing_window_init, gdk_window_foreign_new): Call _gdk_window_init_position() like in the X11 backend. (gdk_window_reparent): Don't call the now nonexistent gdk_window_set_static_win_gravity(). No idea what should be done instead. (gdk_window_get_geometry): The returned x and y should be relative to parent. Used to be always zero.. (gdk_window_set_static_gravities): Return FALSE if trying to set static gravity. * gdk/win32/gdkprivate-win32.h: Drop the clip_region field from GdkGCWin32. Only use the HRGN hcliprgn. Declare new functions. * gdk/win32/*.c: Use new debugging functions. * gdk/win32/rc/gdk.rc.in: Update copyright year.

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.

Reflect recent renamings and removals of functions. 2002-11-15 Tor Lillqvist <tml@iki.fi> * gdk/gdk.def: Reflect recent renamings and removals of functions. Merge from stable: Start implementing all fill styles (i.e. tiled, stippled, and opaque stippled in addition to the plain solid style) in the Win32 backend in an elegant and generic way. For now only did the draw_rectangle() and draw_glyphs() methods. The rest will follow. Previously some of the drawing methods implemented opaque stippling, but not tiles or non-opaque stippling. Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Seems to work fine, now the check marks show up in check buttons, the stippled background and stippled text in gtk-demo's Text Widget look as they should, and GtkText's line wrap arrow shows correctly instead of an ugly rectangle. [This refers to the stable branch, haven't actually checked HEAD.] The implementation does do a lot of pixmap handling and blitting back and forth, especially on Win9x. But performance is hopefully not an issue. I don't think many applications do a lot of tiled or stippled drawing. * gdk/win32/gdkprivate-win32.h: Define a new macro, GDI_CALL, that calls a GDI function and prints a warning if it failed. Also API_CALL for non-GDI calls. Cleans all the the if (!BlaBla()) WIN32_GDI_FAILED ("BlaBla") snippets, these can now be written GDI_CALL (BlaBla, ()). Declare new functions. * gdk/win32/gdkdrawable-win32.c: Use GDI_CALL macro in lots of places. (generic_draw): New function that handles all the blitting necessary to implement tiles and stipples. A function that actually draws stuff is passed as a parameter to generic_draw(). If the fill style is solid, it is called directly, to draw on the destination drawable. Otherwise it is called to draw on a temporary mask bitmap, which then is used in blitting operations. The tiles and/or stipples are rendered into another temporary pixmap. If MaskBlt() is available (on NT/2k/XP), it is used, otherwise a sequence of BitBlt() is used to do the final composition onto the destination drawable. (draw_tiles_lowlevel, draw_tiles): Some renaming and code reorg. Use BitBlt() to blit each tile, not gdk_draw_drawable(). (rop2_to_rop3): New function, does binary->ternary rop mapping. (blit_from_pixmap, blit_inside_window, blit_from_window): Use rop2_to_rop3(). Previously used SRCCOPY always... (draw_rectangle, gdk_win32_draw_rectangle, draw_glyphs, gdk_win32_draw_glyphs): Split functionality into two functions, with generic_draw() doing its magic inbetween. * gdk/win32/gdkevents-win32.c: Remove the TrackMouseEvent code, it was ifdeffed out and wouldn't have done anything even if enabled. Remove the GDK_EVENT_FUNC_FROM_WINDOW_PROC code, didn't have any effect any more anyway after all the changes GTK+ has gone through in the last years. Remove some #if 0 code. * gdk/win32/gdkgc-win32.c (gdk_gc_copy): Set the copy's hdc field to NULL in case a GC is copied while it has a Windows DC active. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Remove gdk_event_func_from_window_proc. * gdk/win32/gdkmain-win32.c: Remove -event-func-from-window-proc option. If there is a PRETEND_WIN9X envvar, set windows_version as if on Win9x. * gdk/win32/gdkpixmap-win32.c (_gdk_win32_pixmap_new, gdk_pixmap_new): Combine these two, _gdk_win32_pixmap_new() wasn't used or exported. Make a bit more like the X11 version. Hopefully I didn't break the fragile palettized display ("pseudocolor") code. * gdk/win32/gdkgc-win32.c: Various debugging output improvements. (predraw_set_foreground): Check whether tile/stipple origins are valid when calling SetBrushOrgEx(). (gdk_win32_hdc_get): Ifdef out code that tries to handle the stipple by converting it into a region, and combining the clip region with that. A stipple shouldn't work like that, it should replicate in x and y directions. Stipples are now handled by generic_draw() in gdkdrawable-win32.c. * gdk/win32/gdkmain-win32.c: (gdk_win32_gcvalues_mask_to_string, gdk_win32_rop2_to_string): New debugging functions. (gdk_win32_print_dc): Print also DC's rop2 and text color.

Massive changes. Too many to list here, but I'll try a summary: 2002-02-17 Tor Lillqvist <tml@iki.fi> * gdk/win32/*.c: Massive changes. Too many to list here, but I'll try a summary: 1) Unify GdkPixmap and GdkImage implementation: For each GdkPixmap, allocate a GdkImage, and vice versa. GdkPixmapImplWin32Data has a pointer to the GdkImage. GdkImage::windowing_data is a pointer to the GdkPixmap. This simplifies many pixmap and image related functions a lot, and reduces duplicated code snippets. For instance, there is only one place in gdk/win32 where CreateDIBSection() is called, in the function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap) to a Windows region is almost trivial, with the bitmap bits being readily accessible in the associated GdkImage. All blitting between GdkPixmaps, GdkWindows and GdkImages goes through handled the _gdk_win32_blit() function, which calls different functions to handle the cases of blitting from pixmaps, inside windows (scrolling), or from windows, which all require somewhat different handling. 2) Support 256-color mode. This has long been very broken, now it works more or less OK. Keep the logical palette for each colormap as small as possible while allocating and freeing colors. Select and realize the logical palette associated with a GdkColormap into a DC before drawing or blitting. When the display is in 256-color mode, make it possible for the user to override the size of the palette(s) used with either the GDK_WIN32_MAX_COLORS environment variable, or a -max-colors command line option. It is possible to reduce the palette size all the way down to using just the 16 static colors (which causes the system visual to be of type GDK_VISUAL_STATIC_COLOR. This could possibly be useful if one desperately wants to avoid color flashing. (Note that in order for this to work properly, an as of yet not commited fix to gdkrgb.c is needed.) Handle the palette messages. On WM_PALETTECHANGED, call UpdateColors() for the given window hierarchy. Do this only if a window in some other top-level window hierarchy caused the palette change (realized a palette). Do this max five times in a row (an arbitrarily chosen limit), though, otherwise redraw by generating expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole window hierarchy by generating GDK_EXPOSE events. 3) Code cleanup in general. For instance, remove the "emulated" X11 structs ColormapStruct, Visual and XStandardColormap. Use the new GDK_DEBUG_* flags for debugging output in the relevant source files. Remove the unused colormap hash table in gdkcolor-win32.c 4) Plug some resource leaks. 2002-02-14 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use g_filename_to_uri() to actually create legal URIs in the text/uri-list data.
