java.lang.Object java.awt.MenuShortcut
public class MenuShortcut
Disabled: no SafeJ information.
The MenuShortcut
class 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()
.
