All Implemented Interfaces:

Direct Known Subclasses:

ColorButton, GradientButton, ImageButton, MarkerButton, PatternButton, TextureButton

public abstract class AbstractButton

extends BorderedWidget

implements org.eclipse.swt.events.MouseListener

Base class for own button implementations. It makes mouse interaction and listener notification more easier. Implementing classes have to overwrite at least the mouseDown() method to specify desired actions and to generate a selection event for listener notification.
