Move here, and save/restore the X error handler to allow people using GTK+
Thu Jan 17 13:08:34 2002 Owen Taylor <otaylor@redhat.com> * gdk/x11/gdkmain-x11.c (gdk_error_trap_push): Move here, and save/restore the X error handler to allow people using GTK+ to set the X error handler to something custom without disturbing the operation of GDK. * gdk/linux-fb/gdkmain-fb.c (gdk_error_trap_push) * gdk/win32/gdkmain-win32.c (gdk_error_trap_pop): Add dummy implementations. * gdk/x11/gdkmain-x11.c gdk/x11/gdkevents-x11.c gdk/x11/gdkdnd-x11.c: Use gdk_error_trap_push()/pop() for all error trapping. * gdk/x11/gdkdnd-x11.c: Remove '#if 0' code. * gdk/x11/gdkdnd-x11.c (gdk_window_cache_new): Fix problem where we would add the results anyways, and then add it again if no error occurred, and problem where we could leave _gdk_error_warnings() unset.
