Parameters:

  • trigger_args (GenericArgs, optional) – Args that are passed to events when they are triggered. This only applies if the listener is not passed.

  • cb (ListenerEventCallbackT | None, optional) – Callback that is invoked when an event is added or removed.

  • listener (ItemListener | None, optional) – Listener that is used to manage events.

  • subscriber (Any, optional) – An UNO object that has a addItemListener() Method. If passed in then this instance listener is automatically added to it. Valid objects are: RadioButton, ComboBox, CheckBox, XItemEventBroadcaster or any other UNO object that has addItemListener() method.

Return type:
