2000-12-30 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkwindow-win32.c
(gdk_window_impl_win32_get_visible_region): New function, as in
the X11 backend.
(gdk_window_new, gdk_window_set_title): Use g_locale_from_utf8()
instead of duplicating the same code here.
* gdk/win32/gdkwin32.h (GDK_COLORMAP_PRIVATE_DATA): Use
GDK_COLORMAP macro.
* gdk/win32/gdkevents-win32.c (gdk_event_funcs): Use NULL as
destroy function.
(gdk_event_translate): Use GDK_COLORMAP_PRIVATE_DATA to correctly
access that.
* gtk/gtk.def: Update.
* gtk/makefile.mingw.in: Use glib-genmarshal from $(GLIB)/gobject.
2000-12-26 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkvisual-win32.c (gdk_visual_init): Call g_error if
we are on a palettized display ("PseudoColor" in X11), as the code
for that doesn't work anyway, and never has.
2000-12-30 Tor Lillqvist <tml@iki.fi>
* gdk_pixbuf.def: Update.
