A scroll button displays one or two arrows. When mouse button 1 (left button) is pressed over an arrow, its callbacks are invoked. The callbacks will be executed continuously as long as the mouse button 1 is pressed. A scroll button has one state variable, the number of times the callbacks has been executed since last button press.
