This example show you how to detect if the Scroll Lock key is in active mode.
package org.kodejava.example.awt;
import java.awt.Toolkit;
import java.awt.event.KeyEvent;
public class ScrollLockState {
public static void main(String[] args) {
Toolkit toolkit = Toolkit.getDefaultToolkit();
//
// Get the locking state of the Scroll Lock button. If it is "on"
// this method return boolean true value.
//
boolean isOn = toolkit.getLockingKeyState(KeyEvent.VK_SCROLL_LOCK);
System.out.println("ScrollLock button is " + (isOn ? "on" : "off"));
}
}
If you run the program you will get an output telling you that the scroll lock button is active or not active.
