Setting button mnemonic key events without having to use ALT

问题

Is there a way to set a button key event in Java so that Alt does not have to be pressed. For example, when this is used setMnemonic(KeyEvent.VK_DELETE) it is required for Alt + Delete to be pressed in the application. How can I get around this? Thanks.

回答1:

I would take a look at the key bindings tutorial. You can specify any KeyStroke to perform any Action.

回答2:

Create a KeyListener, or extend a KeyAdapter. Like this:

private class MnemonicWorkaround extends KeyAdapter{

     @Override
     public void keyPressed(KeyEvent e) {
        int c = e.getKeyCode();
        if(c == KeyEvent.VK_ENTER){
         // do something.
        }
      }
  }

Then add it using component.addKeyListener(new MnemonicWorkaround());
