Mouse Motion Listener
How can i detect when the mose moves when the mouse is not located on the Frame?
Here is my mouse motion listener
privateclass EventHandlerimplements AWTEventListener{
private JPanel myPanel;
public EventHandler(JPanel thepanel){
myPanel = thepanel;
}
publicvoid eventDispatched(AWTEvent event){
if (event.getID() == MouseEvent.MOUSE_MOVED){
MouseEvent me = (MouseEvent)event;
myScreenShooter.setCaptureLocation(me.getX(), me.getY());
myPanel.repaint();
}
}
}
and I register it with a JPanel which I extended
Toolkit.getDefaultToolkit().addAWTEventListener(new EventHandler(this), AWTEvent.MOUSE_MOTION_EVENT_MASK);
But the only time the motion is detected is when the mouse is within the panel...I need to know when it is moved anywhere on the screen.
Any ideas?
Thanks
