C++ (Cpp) GstXOverlayClass::handle_events Beispiele

Beispiel #1

/**
 * gst_x_overlay_handle_events:
 * @overlay: a #GstXOverlay to expose.
 * @handle_events: a #gboolean indicating if events should be handled or not.
 *
 * Tell an overlay that it should handle events from the window system. These
 * events are forwared upstream as navigation events. In some window system,
 * events are not propagated in the window hierarchy if a client is listening
 * for them. This method allows you to disable events handling completely
 * from the XOverlay.
 *
 * Since: 0.10.12
