Direct Known Subclasses:: BasicInternalFrameTitlePane.SystemMenuBar

public class JMenuBar
extends JComponent
implements Accessible, MenuElement
extends JComponent
implements Accessible, MenuElement

An implementation of a menu bar. You add JMenu objects to the menu bar to construct a menu. When the user selects a JMenu object, its associated JPopupMenu is displayed, allowing the user to select one of the JMenuItems on it.

For information and examples of using menu bars see How to Use Menus, a section in The Java Tutorial.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.

Parameters:

ks - the KeyStroke queried

e - the KeyEvent

condition - one of the following values:

JComponent.WHEN_FOCUSED
JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT
JComponent.WHEN_IN_FOCUSED_WINDOW

pressed - true if the key is pressed

Returns:

true if there was a binding to an action, and the action was enabled

Since:

1.3

addNotify

public void addNotify()

Overrides JComponent.addNotify to register this menu bar with the current keyboard manager.
