Action for gesture gestures
<clutter-gesture-action> is a sub-class of
<clutter-action> that implements the logic for recognizing
gesture gestures. It listens for low level events such as
<clutter-button-event> and <clutter-motion-event> on the
stage to raise the <"gesture-begin">,
<"gesture-progress">, and * <"gesture-end"> signals.
To use <clutter-gesture-action> you just need to apply it to a
<clutter-actor> 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-progress", G_CALLBACK (on_gesture_progress), NULL);
g_signal_connect (action, "gesture-end", G_CALLBACK (on_gesture_end), NULL);
