Class java.awt.MenuComponent

java.lang.Object | +----java.awt.MenuComponent
public abstract class MenuComponent
extends Object
implements Serializable
The abstract class MenuComponent is the superclass of all menu-related components. In this respect, the class MenuComponent is analogous to the abstract superclass Component for AWT components.
