Hi,

How does one go about determining the status of Caps Lock and Num Lock in SWT ?

You get them this way:

boolean caps = Toolkit.getDefaultToolkit().getLockingKeyState( java.awt.event.KeyEvent.VK_CAPS_LOCK );
boolean num = Toolkit.getDefaultToolkit().getLockingKeyState( java.awt.event.KeyEvent.VK_NUM_LOCK );
boolean scroll = Toolkit.getDefaultToolkit().getLockingKeyState( java.awt.event.KeyEvent.VK_SCROLL_LOCK );

You may change any of them by doing this:

Toolkit.getDefaultToolkit().setLockingKeyState( java.awt.event.KeyEvent.VK_CAPS_LOCK, boolean );

Hi,

You can't directly determine the state of Numlock & Capslock using SWT. (there is a bug request for it -- https://bugs.eclipse.org/bugs/show_bug.cgi?id=71538).
But, inside the Key Listener you can determine if the key was typed in the numeric keypad with Numlock ON. The event.keyLocation is set to KEYPAD and the event.keyCode is set to the SWT.KEYPAD_* constants.
