How to modify JInternalFrame's iconfying behaviour?

Hi there!
I have a JInternalFrame which I'd like to basically shrink in size when you click on the iconify icon, but not to become an icon. I have set up a listener for iconified, in which I basically first de-iconify, then set the size:

              public void internalFrameIconified(InternalFrameEvent e) {
              try {
              vt.setIcon(false);
              }
              catch (Exception exc) {}
              if (oldHeight == 0) {
                   oldHeight = vt.getHeight();
                   vt.setSize(vt.getWidth(),26);
                    }
              else {
              vt.setSize(vt.getWidth(),oldHeight);
              oldHeight = 0;
              }

              }

This works rather nicely - the problem is just that the iconify icon stays the same - so even when it's "minimized", the iconify button is still there as "minimize".

Is there either a way to change that iconify icon without actually iconifying the window? My problem is that I'm connecting the various windows with lines, so if I iconify one, I get problems if I do more than just set its size.

Thanks ahead of time for any help...

yeah, because the internal frame IS NOT minimized: it's made very small (<> minimized)

So in fact, you're aksing for a method to adapt the minimize/maximize icons...
Mmm... could be difficult. If not impossible, because I guess that's the OS's business.

how and where is that "iconify / maximize" button set? Is there no way to manually switch between the two or something?

PRoviding a custom UI implementation and painting the title bar myself...uh...that sounds a bit complicated. Is it? :-)

not relly, no different than laying out any container really.

I'm afraid not. That icon "follows" the internal frame's state.
That's what 99,99% of the people expect ;°)

What kind of problems?
Maybe you have to rethink this part...

Well, in the end I just had to give up on the iconify button - I now have a context menu "Minimize" and "Restore" respectively, and a double click on the title bar minimizes and restores the window.
The problems i was having, btw, was that the lines lost their reference to the actual frame, since it became hidden, and the icon displayed instead was a different reference.

So, there isn't really a solution to the question, and the first correct answer was from objects. :)
