Some example directly from the above tutorial:
//Setting the mnemonic when constructing a menu item: menuItem = new JMenuItem("A text-only menu item", KeyEvent.VK_H); //Setting the mnemonic after creation time: menuItem.setMnemonic(KeyEvent.VK_H); //Setting the accelerator: menuItem.setAccelerator(KeyStroke.getKeyStroke( KeyEvent.VK_H, ActionEvent.ALT_MASK));
Sample code: (
Alt-H would click the Middle button)
JButton b2 = new JButton("Middle button", middleButtonIcon); b2.setMnemonic(KeyEvent.VK_H);
