Button 

The Button UI element represents the pushbutton on the screen. The user can execute statements and actions by clicking the pushbutton.

To enable the development of accessible applications, the tooltip property is checked during the syntax check if the text property is not set.

A tooltip does not necessarily have to be set for this UI element, but it could make sense to set it if it contains detailed semantic information.
