How to make a JFrame "dumb"...

I am not really proficient in Java, so please excuse if this question is
trivial:

I got an application which consists of several JPanels next to each
other. One of the JPanels has (within its code) some actions defined for
mouse activity within that frame.

What I need: I want to use a "normal" mouse listener on top of that
special JPanel. BUT: the in-built functionalities override my mouse
listener.

So: is there a way to make the "active" panel go dumb (as in: not to
interfere with mouse action) WITHOUT editing this panel's source code?
Like putting an invisible layer on top or the like?

I do need the data this panel displays, but I must not edit the source
code...

Any ideas, hints? Thank you

Steffen

Can't you just extend the JPanel and override anything you don't want?

Depends - that's the way I'd prefer not to go. The class in question has
about 25 methods calling several subclasses and so on, and I do NOT have
the time to follow each trail to see where it leeds and where any action
listeners are implemented... btw, I just looked at the source code and
commented out anything that had actionlistener in it, the display still
works fine, but still no mouse listener for me :-(

Thanks anyway

If your are using Swing, then the "glass pane"  may be useful :

I've been experimenting with this, but so far without success. I do have
the impression that the "active" panel somehow steals all inputs,
although each and every line in there that refers to action listeners
and the like has been commented out...
