How do I get the caps lock state?

[LordOfCode]

I am building a swing application and currently I am working in a status bar for my app.

In this status bar I would like to tell the user what is the caps lock status.

How do I do that?

Thanks in advance!

Well "LordOfCode" ... Look at the KeyListener class ...

 

[LordOfCode]

It's more complicated than that. I already added a keylistener to the MDI form.

How ever I added a keylistener, it just could tell me somebody pressed Caps Lock key, but it cannot tell me if caps lock is on or off.

Any idea how to do so?

I think what you are looking for this getLockingKeyState() method...

i.e...

Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK);

it will return:
Returns whether the given locking key on the keyboard is currently in its "on" state. Valid key codes are VK_CAPS_LOCK, VK_NUM_LOCK, VK_SCROLL_LOCK, and VK_KANA_LOCK.


Hope this helps.

I wrote an exemple but the getLockingKeyState does not work on my machine, FreeBSD5.1.

Don't know about other OS.

The following code worked for me:

import java.awt.*;
import java.awt.event.*;

class Test
{

	public static void main(String[] args)
	{ 
		System.out.println( "Is CAPS LOCK on: " +
		Toolkit.getDefaultToolkit().getLockingKeyState (KeyEvent.VK_CAPS_LOCK) );
		System.out.println( "Is NUM LOCK on: " +
		Toolkit.getDefaultToolkit().getLockingKeyState (KeyEvent.VK_NUM_LOCK) );

	}
}

Thank you very much.
That worked just perfect.
