It is still not that clear what you want to do but you can write a 
listener and then register it with all of the components in your 
application.  You could then determine the component that the mouse was 
over and its position.  You can even determine the absolute position, 
screen coordinates, of the mouse, when the event happened, the name of 
the component, etc.
