public class CJavaMenuItem

extends java.awt.MenuItem

implements java.awt.event.ActionListener

CJavaMenuItem is a subclasses of awt.MenuItem. It is a invisible beans and must be added to a CMenuButton widget. Unlike awt.MenuItem, the action event is already built into this widget. The user does not need to implement the ActionListener.

CJavaMenuItem is used to launch a java application within the same virtual machine. The application is required to provide a static method named execute (String params[]). The name of this application must be set through the setClassName (String javaName) method. If the params[] is used in the execute method, it must be set using setParams (String[] params) method.

The default label for CJavaMenuItem is String "[J]". If user set the label, the "[J] "+label will be the real label to distinguish them from awt.MenuItem.
