public class CMenuButton

extends java.awt.Button

implements java.awt.event.ActionListener

This class creates a stand-alone menu button. It does not need to be added to a menuBar. CMenuBotton looks like a button but works like a menu. When the button is pressed, a pull down menu will appear.

Like awt.Menu, any menuItem, separator and subclass of menuItem such as JavaMenuItem and ShellMenuItem can be added to this widget.

To distinguish from a normal awt.Button, a ">>" String is added on back of the label set by the user. If the label is not set, the default label ">>" will appear on the CMenuBotton.
