Fellow Monks,
I've been running a transparent terminal with no borders displaying 'top' for years now and I'd like to extend the mechanism.

I know that programs like xpenguin, root-tail or root-portal found a way to detect the real root-window of the current X-Session.

For me it would be sufficient to sent the appropriate WindowManagerHint to my Sawfish-WM. I thought it should be possible with PerlGTK but I didn't find a way to do such.

I am not (yet) limited to using PerlGTK, I might as well use the QT or Tk-bindings. I'm just looking for a way to send WM-hints in perl.

Any suggestions?
