Types of UnityGUI input and processing events.

Use this to tell which type of event has taken place in the GUI. Types of Events include mouse clicking, mouse dragging, button pressing, the mouse entering or exiting the window, and the scroll wheel as well as others mentioned below.

Events can be used to prevent other GUI elements from responding to that event. Refer to Event.Use.
