activate

Activates the callback associated to the action that is bound to the key_val and modifiers pair.

The callback has the following signature:

  void (* callback) (GObject             *gobject,
                     const gchar         *action_name,
                     guint                key_val,
                     ClutterModifierType  modifiers,
                     gpointer             user_data);

Where the Object instance is gobject and the user data is the one passed when installing the action with install_action.

If the action bound to the key_val, modifiers pair has been blocked using block_action, the callback will not be invoked, and this function will return false.

Parameters:

this	a BindingPool
key_val	the key symbol
modifiers	bitmask for the modifiers
gobject	a Object

Returns:

true if an action was found and was activated
