Original commit message from CVS: 2007-01-04 Julien MOUTTE <julien@moutte.net> * gst-libs/gst/interfaces/xoverlay.c: (gst_x_overlay_handle_events): * gst-libs/gst/interfaces/xoverlay.h: * sys/ximage/ximagesink.c: (gst_ximagesink_xwindow_new), (gst_ximagesink_set_xwindow_id), (gst_ximagesink_set_event_handling), (gst_ximagesink_xoverlay_init), (gst_ximagesink_set_property), (gst_ximagesink_get_property), (gst_ximagesink_init), (gst_ximagesink_class_init): * sys/ximage/ximagesink.h: * sys/xvimage/xvimagesink.c: (gst_xvimagesink_xwindow_new), (gst_xvimagesink_set_xwindow_id), (gst_xvimagesink_set_event_handling), (gst_xvimagesink_xoverlay_init), (gst_xvimagesink_set_property), (gst_xvimagesink_get_property), (gst_xvimagesink_init), (gst_xvimagesink_class_init): * sys/xvimage/xvimagesink.h: * tests/icles/stress-xoverlay.c: (toggle_events), (create_window): Add a method to the XOverlay interface to allow disabling of event handling in x[v]imagesink elements. This will let X events propagate to parent windows which can be usefull in some cases. Be carefull that the application is then responsible of pushing navigation events and expose events to the video sink. Fixes: #387138.
