How to add hotkey (F12) to a button?

[steven.smith]

Hey there all. I need to find out how to add a hotkey to a button (F12 key) so that it activates and deactivates when they hotkey is pressed or released.

The script is:

    

}
    JButton button = new JButton("Press This Button to Talk");

    button.addMouseListener(this);

    add(button);

    setSize(new Dimension(300, 100));

  }

Thanks for any and all help. It is really appreciated.

Check out the AbstractButton API and look up a method that contains the word mnemonic in it. That will help you assign an alt+keystroke combination to a JButton. If you want to associate a non-alt-keystroke combination to a JButton, you'll want to use Key Bindings, and the Java tutorials will show you how to do this.

The Swing tutorial has a section on: How to Use Key Bindings (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)

Thanks for both of your responses. As per suggestions, would this work?

}
    JButton button = new JButton("Press This Button to Talk");
 
    button.addMouseListener(this);
 
    add(button);

    setSize(new Dimension(300, 100));

    component.getInputMap().put(KeyStroke.getKeyStroke("F12"),
                            "pressed");

    component.getInputMap().put(KeyStroke.getKeyStroke("released F12"),
                            "released");

    component.getActionMap().put("pressed",
                             pressedAction);

    component.getActionMap().put("released",
                             releasedAction);
  }

I just wanted a shortcut key that has the same effect as pressing the button with the mouse. The button is meant to listen for voice while the mouse button is pressed down on it and to stop listening when the mouse is released. This is what I wanted the hotkey to do as well.

We're not your compiler. Run the code, test the code, report back if you have errors or it doesn't work.

I was asking more if the syntax seemed correct... with that said I'm trying it now :)

Well, you shouldn't be adding a MouseListener to a JButton but rather an ActionListener -- please have a look at the tutorials regarding how to use buttons. Also, where did you get the "Released F12" String from? -- I've never seen that one before, and highly suspect that it won't work.

Also, this is in no way an advanced topic. If you have a non-GUI question of this level, please post in 'New to Java'
