ooodev.adapter.form.update_events.on_lazy_cb(source, event)[source]

Callback that is invoked when an event is added or removed.

This method is generally used to add the listener to the component in a lazy manner. This means this callback will only be called once in the lifetime of the component.

Parameters:

source (Any) – Expected to be an instance of UpdateEvents that is a partial class of a component based class.
event (ListenerEventArgs) – Event arguments.

Return type:

None
