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.

New debugging function, to log a clipboard format name symbolically. 2005-04-04 Tor Lillqvist <tml@novell.com> * gdk/win32/gdkmain.c (_gdk_win32_cf_to_string): New debugging function, to log a clipboard format name symbolically.

(gdk_selection_property_get): We should append a zero byte like X11 does. (gdk_win32_selection_add_targets): New function, for gtkselection's use. Win32 requires that the clipboard owner registers all valid formats even if the owner wants delayed rendering. (_gdk_win32_selection_convert_to_dib): New function. Convert images to DIB using gdk-pixbuf. * gdk/win32/gdkwin32.h: Declare gdk_win32_selection_add_targets(). * gtk/gtkselection.c (gtk_selection_add_target, gtk_selection_add_targets): Call gdk_win32_selection_add_targets() to register target formats. * gdk/gdk.symbols: Add gdk_win32_selection_add_targets().

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.

gdk/win32/gdkprivate-win32.h New flags _gdk_input_locale_is_ime and 2003-07-25 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: New flags _gdk_input_locale_is_ime and _gdk_keyboard_has_altgr. * gdk/win32/gdkevents-win32.c: Lots of changes. Most important ones detailled here. Code that has been ifdeffed out for a long time removed. Remove some really old doc comments that were left behind for some public functions, the official ones are in the X11 backend anyway. Change GDK_WINDOW_OBJECT() calls to GdkWindowObject casts. Reformat multi-line boolean expressions to have the operators at ends of lines. As mouse capture with SetCapture() indeed seems to work OK, no need to have the correspoinding macro USE_SETCAPTURE and ifdefs. Ifdef out the gdk-ping-msg stuff. I don't remember why it was needed at some time, and things seem to work fine now without (knock on wood). Ifdef out the search for some Latin locale keyboard layout being loaded. Not used currently, but might be needed after all, if we decide that we want to be able to generate ASCII control character events with a non-Latin keyboard. (assign_object): New helper function, handles the g_object_ref() and unref() calls when assigning GObject pointers. (generate_crossing_events): Also generate the GDK_NOTIFY_INTERIOR enter event when the pointer has moved to an ancestor window. Was left out by mistake. (gdk_window_is_ancestor): Renamed from gdk_window_is_child(). (gdk_pointer_grab, gdk_pointer_ungrab): Implement the confine_to functionality, using ClipCursor(). (find_window_for_mouse_event): Splice part of code into new function find_real_window_for_grabbed_mouse_event(). (fixup_event, append_event, apply_filters): New functions, code refactored out from elsewhere. (synthesize_enter_or_leave_event, synthesize_leave_event, synthesize_enter_event, synthesize_leave_events,synthesize_enter_events): Also take a GdkCrossingMode parameter, in preparation to generating GDK_CROSSING_GRAB and GDK_CROSSING_UNGRAB events. (fixup_event, append_event, fill_key_event_string): New functions, code refactoring. (vk_from_char, build_keypress_event, build_keyrelease_event): Removed as part of dropping WM_CHAR handling. (build_key_event_state,gdk_event_translate): Call GetKeyboardState(), once, for each keyboard message, instead of several calls to GetKeyState() here and there. (gdk_event_translate): Fix bugs #104516, #104662, #115902. While at it, do some major refactoring, and some fixes for potential problems noticed while going through the code. Don't handle WM_CHAR at all. Only handle WM_KEYDOWN and WM_KEYUP. Don't need the state variables related to whether to wait for WM_CHAR or not, and whether the current key is AltGr. Remove lots of complexity. Thus don't need the use_ime_composition flag. Not handling WM_CHAR means dead key handling will have to be taken care of by GTK, but that seems to work fine, so no worry. Another side-effect is that Alt+keypad digits don't work any longer, but it's better to learn to use GTK's ISO14755 support is anyway. Be more careful in checking whether AltGr is involved. Only attempt to handle it if the keyboard actually has it. And explicitly check for *left* Control plus *right* Alt being pressed. Still, allow (left) Alt and/or (right) Control with AltGr chars. Handle keys using similar code as in the X11 backend. As we have built a keymap in gdkkeys-win32.c anyway, use it by calling gdk_keymap_translate_keyboard_state() to look up the keysym from the virtual key code and keyboard state. Build the key event string in exactly the same way as the X11 backend. If an IME is being used, don't generate GDK events for keys between receiving WM_IME_STARTCOMPOSITION and WM_IME_ENDCOMPOSITION, as those keys are for the IME. For WM_IME_COMPOSITION, handle all the Unicode chars returned from the IME, not just the first one. gdk_event_translate() is still quite complex, could split the message handler cases out into separate functions. On mouse events, when the mouse is grabbed, use find_real_window_for_grabbed_mouse_event() in order to be able to generate correct crossing events. No longer take a pre-allocated GdkEvent as parameter. Instead, allocate events as needed and append them to the queue. (This is different from how gdk_event_translate() in the X11 backend works.) This change made the code much clearer, especially in the cases where we have to generate several GDK events for one Windows message. Return FALSE if DefWindowProc() should be called, TRUE if not. If DefWindowProc() should not be called, also return the value to be returned from the window procedure. (Previously, the interaction with gdk_event_translate()'s caller was much more complex, when we had to indicate whether the already-queued event should be left in the queue or removed, and in addition also had to indicate whether to call DefWindowProc() or not, and what value to return from the window procedure if not.) Don't use a separate "private" variable required to be pointing to the GdkWindowObject of the "window" variable at all times. Just use casts, even if looks a bit uglier. Notice destroyed windows as early as possible, and break out of the messsage switch. Use _gdk_pointer_root as current_window when the pointer is outside GDK's top-level windows. On WM_INPUTLANGCHANGE, set _gdk_input_locale_is_ime as appropriate, based on ImmIsIME(). (gdk_event_translate, gdk_event_send_client_message_for_display, gdk_screen_broadcast_client_message): Implement client messages. Use a registered Windows message to pass GDK client messages. Note that the amount of user data is restricted to four bytes, as it is carried in the LPARAM. (The WPARAM is used for the message type "atom".) (real_window_procedure): Adapt for new gdk_event_translate() interface. * gdk/win32/gdkmain-win32.c (_gdk_windowing_init): Set _gdk_input_locale_is_ime initially. * gdk/win32/gdkwindow-win32.c: Use g_object_ref()/unref() instead of g_colormap_ref()/unref(). (gdk_window_new): Made code a bit more like the X11 one, pretend to handle screens (although we just have one for now). * gdk/x11/gdkevents-x11.c (gdk_event_send_client_message_for_display, gdk_screen_broadcast_client_message): Document the user data limitation on Win32. * gdk/win32/gdkevents-win32.c (print_event): More complete enter and leave notify detail output. * gdk/win32/gdkkeys-win32.c (update_keymap): Make dead keys visible to GDK and GTK. Store the corresponding GDK_dead_* keysym for those, so that the GtkIMContextCimple compose tables will work. Deduce if the keyboard layout has the AltGr key, and set the above flag accordingly.

Bug 559408 - Transparency lost when images are copied between GTK+ and the 2009-01-29 Tor Lillqvist <tml@novell.com> Bug 559408 - Transparency lost when images are copied between GTK+ and the clipboard on Windows The code in gdkselection-win32.c is simplified quite a lot. When an image is stored on the clipboard from GTK+, only the "PNG" and CF_DIB formats are advertised. PNG is our preferred format because it can losslessly represent any image that gdk-pixbuf can handle, even with alpha, unambiguously. CF_DIB is also advertised because of its ubiquitous support in Windows software. Delayed rendering is used as before, so for other data than text nothing is actually stored on the clipboard until some app asks for it. It's pointless to advertise images formats like "image/png" or "image/x-MS-bmp" that no other Windows application is going to look for anyway. Likewise it's pointless to store text under formats like "text/plain" or "UTF8_STRING". Just store CF_UNICODETEXT. CF_TEXT will be available as a synthesized format anyways. Office 2007 offers and asks for images in PNG format using the registered clipboard format name "PNG", so we do likewise. If the "PNG" format is available that is preferred when copying to GTK+ from the clipboard. Unfortunately Word 2007 still uses CF_DIB without handling alpha. But PowerPoint 2007 uses PNG if available and handles alpha correctly. Both Word and Powerpoint offer PNG with alpha nicely. Firefox and IE7 offer images that contain alpha as 32-bit version 3 BI_RGB DIBs with the undocumented "extra" bytes actually being alpha. Also, alpha is premultiplied into the RGB bytes, presumably because that is how AlphaBlend() wants such DIBs. That is also taken care of. At least for Firefox it easy to be sure that a CF_DIB on the clipboard is from Firefox. Also some general stylistic cleanup, comment improvements, and improvements of debugging printout especially in the clipboard handling. Those are not detailled below. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c * gdk/win32/gdkgmain-win32.c: Move some globals that were used only in gdkselection-win32.c to be local to that file. * gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't bother checking if text to be placed on the clipboard consists of only ASCII. * gdk/win32/gdkselection-win32.c: Add static variables for a list of GdkPixbuf-supported formats, well-known registered clipboard formats for images, and for GdkAtoms for well-known image and text formats. (_gdk_win32_selection_init): Initialize above static variables. (selection_property_store) (gdk_selection_property_get) (_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps for a window after all, it breaks testtext. See bug #163844. (gdk_selection_convert): When converting to the TARGETS format, i.e. when the caller wants to know what clipboard formats are available, if PNG is available we report just that and skip CF_DIB, JPEG and GIF even if advertised. If CF_UNICODETEXT is available, report only UTF8_STRING. When converting to the UTF8_STRING format, i.e. when the caller wants text from the clipboard, try just CF_UNICODETEXT. There is no point in trying CF_TEXT as Windows will synthesize CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just CF_TEXT. When converting to the image/bmp format, i.e. when the caller wants an CF_DIB image from the clipboard, we check if the DIB is a version 3 32-bit BI_RGB one that is likely to actually contain alpha in the "extra" bytes. Such a DIB is likely to have premultiplied alpha even, at least in the case of Firefox 3 and IE7. We then edit the DIB in-place into a version 5 one in BI_BITFIELDS format and undo the alpha premultiplication. In any case, prepend a BMP file header before letting go of the data which will be fed to the gdk-pixbuf bmp loader by upper levels. (gdk_win32_selection_add_targets): If some kind of pixmap image format is being added, actually advertise just PNG and CF_DIB. Note that alpha won't be stored on the clipboard through CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save alpha. Furthermore, few if any non-GTK+ Windows apps seem to understand a version 5 DIB with proper alpha anyway. (_gdk_win32_selection_convert_to_dib): Simplified muchly. svn path=/trunk/; revision=22255

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.

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.

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.

New debugging function, to log a clipboard format name symbolically. 2005-04-04 Tor Lillqvist <tml@novell.com> * gdk/win32/gdkmain.c (_gdk_win32_cf_to_string): New debugging function, to log a clipboard format name symbolically. (_gdk_win32_data_to_string): Also new, to log random data bytes. 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. (gdk_selection_property_get): We should append a zero byte like X11 does. (gdk_win32_selection_add_targets): New function, for gtkselection's use. Win32 requires that the clipboard owner registers all valid formats even if the owner wants delayed rendering. (_gdk_win32_selection_convert_to_dib): New function. Convert images to DIB using gdk-pixbuf. * gdk/win32/gdkwin32.h: Declare gdk_win32_selection_add_targets(). * gtk/gtkselection.c (gtk_selection_add_target, gtk_selection_add_targets): Call gdk_win32_selection_add_targets() to register target formats. * gdk/gdk.symbols: Add gdk_win32_selection_add_targets().
