2004-05-18 Matthias Clasen <mclasen@redhat.com> * configure.in: Check for XFIXES extension. * gdk/x11/gdkdisplay-x11.h (struct _GdkDisplayX11): Add a gboolean have_xfixes member. * gdk/x11/gdkdisplay-x11.c (gdk_display_open): Register XFIXES events and set have_xfixes. * gdk/gdkevents.h (GdkEventType): Add GDK_OWNER_CHANGE. (GdkEventOwnerChange): New event struct for owner change events. (GdkOwnerChange): New enum for the reason field of GdkEventOwnerChange. * gdk/x11/gdkevents-x11.c (gdk_event_translate): Translate XFixesSelectionNotify events into GdkEventOwnerChange events. * gdk/gdkdisplay.h: * gdk/x11/gdkdisplay-x11.c (gdk_display_supports_selection_notification): (gdk_display_request_selection_notification): New api to support selection ownership notification. * gtk/gtkclipboard.h: * gtk/gtkclipboard.c (_gtk_clipboard_handle_event): New private api to handle owner change events. (clipboard_peek): Refactored out the body of gtk_clipboard_get_for_display() for use in _gtk_clipboard_handle_event(). * gtk/gtkmain.c (gtk_main_do_event): Handle GDK_OWNER_CHANGE events by calling _gtk_clipboard_handle_event().
