MenuShortcut (Java Platform SE 6) - JDK 5 Documentation v6.0, Java 2 SDK 英文文档


Java™ Platform

java.awt
Class MenuShortcut

java.lang.Object
  extended by java.awt.MenuShortcut
All Implemented Interfaces:
Serializable

public class MenuShortcut
extends Object
implements Serializable

The MenuShortcutclass represents a keyboard accelerator for a MenuItem.

Menu shortcuts are created using virtual keycodes, not characters. For example, a menu shortcut for Ctrl-a (assuming that Control is the accelerator key) would be created with code like the following:

MenuShortcut ms = new MenuShortcut(KeyEvent.VK_A, false);

The accelerator key is platform-dependent and may be obtained via Toolkit.getMenuShortcutKeyMask().

JDK1.1

Constructor Summary
MenuShortcut(int key)
          Constructs a new MenuShortcut for the specified virtual keycode.
MenuShortcut(int key, boolean useShiftModifier)

          Returns whether this MenuShortcut is the same as another: equality is defined to mean that both MenuShortcuts use the same key and both either use or don't use the SHIFT key.
 boolean equals(Object obj)
          Returns whether this MenuShortcut is the same as another: equality is defined to mean that both MenuShortcuts use the same key and both either use or don't use the SHIFT key.
 int getKey()
          Returns the raw keycode of this MenuShortcut.
 int hashCode()
          Returns the hashcode for this MenuShortcut.
protected  String paramString()
          Returns the parameter string representing the state of this MenuShortcut.
 String toString()
          Returns an internationalized description of the MenuShortcut.
