Class MenuShortcut

Contents
  • 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);

    or alternatively

    MenuShortcut ms = new MenuShortcut(KeyEvent.getExtendedKeyCodeForChar('A'), false);

    Menu shortcuts may also be constructed for a wider set of keycodes using the java.awt.event.KeyEvent.getExtendedKeyCodeForChar call. For example, a menu shortcut for "Ctrl+cyrillic ef" is created by

    MenuShortcut ms = new MenuShortcut(KeyEvent.getExtendedKeyCodeForChar('?'), false);

    Note that shortcuts created with a keycode or an extended keycode defined as a constant in KeyEvent work regardless of the current keyboard layout. However, a shortcut made of an extended keycode not listed in KeyEvent only work if the current keyboard layout produces a corresponding letter.

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