|
||||
* @Title: ClutterGestureAction
|
||||
* @Short_Description: Action for gesture gestures
|
||||
*
|
||||
* #ClutterGestureAction is a sub-class of #ClutterAction that implements
|
||||
* the logic for recognizing gesture gestures. It listens for low level events
|
||||
* such as #ClutterButtonEvent and #ClutterMotionEvent on the stage to raise
|
||||
* the signals #ClutterGestureAction::gesture-begin, #ClutterGestureAction::gesture-motion and
|
||||
* #ClutterGestureAction::gesture-end.
|
||||
*
|
||||
* To use #ClutterGestureAction you just need to apply it to a #ClutterActor
|
||||
* using clutter_actor_add_action() and connect to the signals:
|
||||
*
|
||||
* |[
|
||||
* ClutterAction *action = clutter_gesture_action_new ();
|
||||
*
|
||||
* clutter_actor_add_action (actor, action);
|
||||
*
|
||||
* g_signal_connect (action, "gesture-begin", G_CALLBACK (on_gesture_begin), NULL);
|
||||
* g_signal_connect (action, "gesture-motion", G_CALLBACK (on_gesture_motion), NULL);
|
||||
* g_signal_connect (action, "gesture-end", G_CALLBACK (on_gesture_end), NULL);
