Determine which frame called windowActivated

I have a number of JFrames that call the same
windowActivated(WindowEvent we). How do I determine which frame caused
the event.

Thanks.

Ben.

I haven't yet used windowActivated, but would this work?

Object src = we.getSource();

if(src == oneJFrame){
doStuff();
}else if(src == otherJFrame){
doSomethingElse();
}

The best would be to provide them with separate event handlers. What is
the point in first merging something (the otherwise independent events),
and then trying to separate things once they are merged?

If you really want to mess with one handler only, evaluate the event's
source.
