UIEvent

The UIEvent interface represents simple user interface events.

UIEvent derives from Event. Though the UIEvent.initUIEvent() method is kept for backward compatibility, creating of a UIEvent object should be done using the UIEvent() constructor.

Several interfaces are direct or indirect descendants of this one: MouseEvent, FocusEvent, KeyboardEvent, WheelEvent, InputEvent, and CompositionEvent.
