public class MenuShortcut extends Object implements Serializable
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);
The accelerator key is platform-dependent and may be obtained
via Toolkit.getMenuShortcutKeyMask()
.
