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>.
