java.lang.Object java.awt.MenuComponent
public abstract class MenuComponent
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.
Menu components receive and process AWT events, just as components do, through the method processEvent.

public void setFont(Font f)
Some platforms may not support setting of all font attributes of a menu component; in such cases, calling setFont will have no effect on the unsupported font attributes of this menu component. Unless subcomponents of this menu component specify a different font, this font will be used by those subcomponents if supported by the underlying platform.
