MouseListener on JFrame

Question

I want to receive notifications about mouse events (in particular, about mouse input and exit) on my JFrame. But when I add a mouselistener to it, I get events at the borders of the frame, and not the whole frame with its contents.

Any ideas as to why?

EDIT: Or at least do you have an alternative? I want a “cloudy” way to catch mouse events on a JFrame. Maybe a mouselistener is not the answer.

Answer 1

You can get all the events and check if their source is a component in the JFrame.

See Toolkit.addAWTEventListener
