UIEvent

The UIEvent interface represents simple user interface events.

UIEvent derives from Event. Although the UIEvent.initUIEvent() method is kept for backward compatibility, you should create a UIEvent object using the UIEvent() constructor.

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