True if the action should be performed, False otherwise.

When approveAction event is invoked it will contain a CancelEventArgs instance as the trigger event. When the event is triggered the CancelEventArgs.cancel can be set to True to cancel the action. Also if canceled the CancelEventArgs.handled can be set to True to indicate that the action should be performed. The CancelEventArgs.event_data will contain the original com.sun.star.lang.EventObject that triggered the update.

disposing(Source)[source]

Gets called when the broadcaster is about to be disposed.

All listeners and all other objects, which reference the broadcaster should release the reference to the source. No method should be invoked anymore on this object ( including XComponent.removeEventListener() ).

This method is called for every listener registration of derived listener interfaced, not only for registrations at XComponent.

Return type:

None
