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().

/* We emulate the GDK_SELECTION window properties of windows (as used
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.

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.

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.

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.

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.

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_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.

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.

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>.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.)

(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.

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.

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.

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.

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.

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.

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.

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.

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().

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.

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.

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.

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/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_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.

(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.

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.

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.

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.

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.

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.

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.

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.

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.

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. 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.

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.

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.

PNG is our preferred format because it can losslessly represent any image that gdk-pixbuf can handle, even with alpha, unambiguously.

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.

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.

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.

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.
