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.

int _gdk_offset_x, _gdk_offset_y;
gdk/win32/gdkinput-win32.h Drop the GdkEvent* parameter, it wasn't used. 2003-08-07 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkinput-win32.h * gdk/win32/gdkinput-win32.c (_gdk_input_configure_event, _gdk_input_enter_event): Drop the GdkEvent* parameter, it wasn't used. * gdk/win32/gdkevents-win32.c (gdk_event_translate): Adapt caller accordingly, in fact an uninitialised variable was dereferenced. [Win32] Add support for multiple monitors. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: New global variables for multiple-monitor info: _gdk_num_monitors, _gdk_monitors, and _gdk_offset_x and _gdk_offset_y. * gdk/win32/gdkdisplay-win32.c (count_monitor, enum_monitor): New functions, enumeration functions passed to EnumDisplayMonitors(). (gdk_display_open): If the EnumDisplayMonitors() and GetMonitorInfo() API is present (on Win98, Win2000 and newer), use if to find out monitor info. Calculate the offset between Win32 coordinates (relative to the primary monitor's origin (and thus negative on monitors to the left of or above it), and GDK's (visible coordinates should be non-negative). * gdk/win32/gdkscreen-win32 (gdk_screen_get_n_monitors, gdk_screen_get_monitor_geometry): Use information collected above. (gdk_window_move, gdk_window_move_resize_window_get_geometry): Subtract _gdk_offset_{x,y} from GDK root window coordinates. (gdk_window_get_geometry, gdk_window_get_origin, gdk_window_get_frame_extents): For top-level windows, add _gdk_offset_{x,y} to GDK root window coordinates Still need to handle multiple monitors in gdk_window_fullscreen(). Probably should make the window fullscreen on the monitor where the cursor is? * gdk/win32/gdkevents-win32.c: Add _gdk_offset_{x,y} to all GDK root window coordinates in GdkEvents. [Win32] Fix geometry hint handling. Add support for resize increment and base size, and aspect ratio geometry hints. The "gridded geometry" test in testgtk now works beautifully. * gdk/win32/gdkwindow-win32.c (gdk_window_set_geometry_hints): Turns out this function shouldn't actually ever modify the window's size, just store the hints. (Old code kept for a while inside #if 0.) (gdk_window_set_hints): Remove presumably broken code that handles the position hints, this function is obsolete anyway. * gdk/win32/gdkevents-win32.c: Drop the current_{x,y}_root variables, not used. (adjust_drag): New function, used to implement resize increment hints. (gdk_event_translate): Handle WM_SIZING, implement resize increment and base size, and aspect ratio geometry hints here. The WM_GETMINMAXINFO handler takes care of the minimum and maximum size hints as before. Fix the WM_GETMINMAXINFO handler to take into account window decorations. No need to modify the ptMaxPosition and ptMaxSize fields in the MINMAXINFO struct, the defaults are fine. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkwindow-win32.c (_gdk_win32_adjust_client_rect, _gdk_win32_get_adjusted_client_rect): New helper functions.
2003-08-07 22:17:18 +00:00
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.

Apply the same fixes and improvements as to the gtk-1-3-win32-production 2002-01-10 Tor Lillqvist <tml@iki.fi> Apply the same fixes and improvements as to the gtk-1-3-win32-production branch: Bug fixes and cleanup of selection and DND functionality. Still doesn't work as well as the win32-production branch, though, but getting closer. After this, need to add Archaeopteryx Software's OLE2 DND support. * gdk/win32/gdkselection-win32.c (gdk_selection_owner_set, gdk_selection_send_notify, generate_selection_notify): Don't use SendMessage() to generate events for the same app, instead use gdk_event_put(). * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c * gdk/win32/gdkmain-win32.c * gdk/win32/gdkevents-win32.c: Thus, remove declaration, definition, initialisation and handling of gdk_selection_notify_msg, gdk_selection_request_msg and gdk_selection_clear_msg. * gdk/win32/gdkselection-win32.c (gdk_text_property_to_text_list, gdk_free_text_list, gdk_string_to_compound_text, gdk_free_compound_text): Implement trivially, witrh a text_list always having a single element, and a compound text always consisting of just a single (UTF-8!) string. Let's see how well this works. * gdk/win32/gdkselection-win32.c (gdk_selection_convert): Fix non-ASCII paste from the clipboard: Try getting the same formats from the Windows clipboard that gdk_property_change() puts there: CF_UNICODETEXT, UTF8_STRING or CF_TEXT+CF_LOCALE. * gdk/win32/gdkproperty-win32.c (gdk_property_change): When storing text on the clipboard, handle non-ASCII text correctly. The logic is as follows: If we have only ASCII characters, use CF_TEXT. Else, if we are on NT, use CF_UNICODETEXT. Else (we are on Win9x), if all the characters are present in the code page of some installed locale, use CF_TEXT and also set CF_LOCALE to that locale. Else (still on Win9x) store as RTF. We use a very simple RTF string, just the text, no fonts or other crap, with the non-ASCII characters as Unicode \uN keywords. Additionally, also store the UTF-8 string as such, under the format "UTF8_STRING", so that GDK can also paste from the Clipboard what it has copied there. (Thus no need to implement any RTF parser.) (find_common_locale): New function, implements the search for a locale for case 3 above. * gdk/win32/gdkglobals-win32.c: New global variables compound_text, text_uri_list, utf8_string, cf_rtf and cf_utf8_string. * gdk/win32/gdkim-win32.c (_gdk_ucs2_to_utf8): New function, converts from a wchar_t string to UTF-8. (_gdk_utf8_to_ucs2): Rename from _gdk_win32_nmbstowchar_ts. (_gdk_utf8_to_wcs): Rename from gdk_nmbstowchar_ts. * gdk/win32/gdkevents-win32.c (build_keypress_event): Use _gdk_ucs2_to_utf8(). * gdk/win32/gdkselection-win32.c: Remove some unnecessary logging. * gdk/win32/gdkdnd-win32.c: Plug memory leaks, the gdk_drag_context_ref() was called unnecessarily in a couple of places, meaning drag contexts were never freed. The same memory leaks seem to be present in gdk/linux-fb/gdkselection-fb.c, BTW. (gdk_drop_reply): For WIN32_DROPFILES drops, free the temporarily stored file list. * gdk/win32/gdkselection-win32.c: Clarify the use of the sel_prop_table. Now it is used only for storing the GDK_SELECTION "properties". The file names dropped with WM_DROPFILES -style DND is stored temporarily (between the drop and the target picking them up) in a separate place. Have a separate hash table to map selection atoms to owner windows. This used to be quite mixed up. (_gdk_dropfiles_store): New function, to store the dropped file list for the drop target to possibly fetch, and clear it afterwards, from gdk_drop_reply(). (gdk_selection_owner_get): Much simplified now.

Implement the functions that until now just were non-functional stubs. For 2002-02-26 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkkeys-win32.c: Implement the functions that until now just were non-functional stubs. For "hardware keycodes", we use Windows virtual keycodes. Not scancodes, although that at first might seem more low-level and a better match to X11 keycodes. The Windows API is really mixed up and confused with respect to scancodes and virtual keycodes. (Surprised?) Some scancodes are generated by two keys on the keyboard (!), and although the keyboard messages do have a flag to indicate which key the user pressed, other API that take a scan code as input don't let you specify which actual key you mean. (update_keymap): Function to build a X11-like representation of the keyboard. Each key has four keysyms: two levels (nonshifted and shifted) and two groups (normal and with AltGr). (gdk_keymap_get_direction): Use the codepage corresponding to the thread's input locale, not the system codepage. * gdk/win32/gdkglobals-win32.c * gdk/win32/gdkmain-win32.c * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkwindow-win32.h * gdk/win32/gdkwindow-win32.c: Remove the input_locale and charset_info fields from GdkWindowImplWin32. Input locale is per-thread in Windows, and as GDK on Windows really only works when the GDI interaction all happens in just one thread anyway, this state can be global. Use globals _gdk_input_locale and _gdk_input_codepage instead. Set these based on the thread's input locale (keyboard layout, or which IME is active). * gdk/win32/gdkevents-win32.c: Set the group and hardware_keycode fields in GDK key events. On input locale change messages, set the global state variables, and inform update_keymap() that it has to rebuild the keymap.

Implement delayed rendering on Win32, specifically for transfering images through the clipboard from GTK+ apps to other apps (#168173, implementation by Ivan Wong): * gdk/win32/gdkevents-win32.c (gdk_event_translate): Handle WM_RENDERFORMAT. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Add _format_atom_table, _delayed_rendering_data and _image_bmp. * gdk/win32/gdkmain-win32.c: Initialize _image_bmp. * gdk/win32/gdkproperty-win32.c (gdk_property_change): Accept formats other than GDK_TARGET_STRING or _utf8_string, and assume they are handled through delayed rendering. * gdk/win32/gdkselection-win32.c (gdk_selection_convert): Return all available formats (including those registered by GTK+ apps) on request_targets.
