the Java Look and Feel design guidelines state that the default command button of a top level container (JFrame, JDialog) and also the cancel/exit button should not have keyboard mnemonics. Suppose you have a File|Exit menu item and an Exit command button. I setup an Action (extends from AbstractAction) for both the menu item and the exit button. I also setup a mnemonic for the Action by using the method putValue(MNEMONIC_KEY, KeyEvent.VK_X). The problem is that now both the menu item and the exit command button have a mnemonic, while according to the L&F guidelines the exit button shouldn't ! How do you suggest to solve this dilemma ?
