2001-06-19 Havoc Pennington <hp@pobox.com> * gdk/x11/gdkwindow-x11.c (gdk_window_show_unraised): new function for mapping a window without fooling with stacking order, but updating the "withdrawn" flag * gdk/x11/gdkevents-x11.c (gdk_event_translate): Do event filtering as soon as possible, moving move resize and wmspec_check handling after the event filter. Make default filter apply to all events, not just those with no GdkWindow wrapped around the X window. Fix a FIXME about how the window could be a pixmap using RTTI; this of course assumes GDK_IS_WINDOW() is optimized. Also, be robust against events not on a known GdkWindow. * gdk/x11/gdkmain-x11.c (gdk_x11_grab_server, gdk_x11_ungrab_server): export reference-counted server grabs, so other people can grab server over a GDK function that also does so.
