public class Counter
extends EmitComponent
implements VisualComponent, EventLabels

A bounded counter implemented as a JavaBean with Trull support only for event emission. The current value of the counter is visualized as the position of a button in a rectangle whose height is the maximum value times the height of the button. The counter emits OUCH when the maximum value is reached and PRESSED when the button is pressed.
