Field Detail

key

int key

The virtual keycode for the menu shortcut. This is the keycode with which the menu shortcut will be created. Note that it is a virtual keycode, not a character, e.g. KeyEvent.VK_A, not 'a'. Note: in 1.1.x you must use setActionCommand() on a menu item in order for its shortcut to work, otherwise it will fire a null action command.
