ctrl-tab shift-ctrl-tab in MDI application

I have an MDI app using JInternalFrame and JDesktopPane, and I'd like
to use ctl-tab/shift-ctl-tab (on Windows with Win l&f) to move between
the internal frames instead of the default ctl-f6. But I have been
unable to intercept the ctrl-tab which seems to have been snapped up
somewhere in the swing framework.

I'd originally assumed I'd have to do something with input maps and
action maps, but no matter what I attach them to, I don't manage to
pick up the ctrl-tab keypresses.

Has anyone else tried this and got it to work, either using action
maps or processKeyEvent?

Regards

Steve

Those keys have probably been pilfered by the focus management system.
There may be a way to convince the focus manager to let go of them,
but I can't remember.

If I'm right, you should keep in mind that if you redefine them, you
may ruin keyboard navigation in your app.

Yes, there is. Take a look a the setFocusTraversalKeys(int, Set)
method in java.awt.Container.
