Different panel applet on each workspace?!

[Henrik Brink <hb pro-it dk>]

Hello!

I'm writing a panel applet for gnome using python. 

I want this applet to display different content on each workspace. How
do I do that?

I've tried to connect the gdk root window to the property-notify-event
in the hope that it would pick up the change in _NET_CURRENT_DESKTOP
when the user switches workspace, but it does not.

Can this be done using libwnck? Is that the only way? I would like to
find another way because libwnck has no python bindings.

Thanks in advance...
