Re: window / workspace switcher

[Milan Bouchet-Valat <nalimilan club fr>]

I wrote a little patch some time ago that I'll need at some point. It's
not been committed into metacity-clutter, but I think it can easily go
there if you need it now.

The relevant code is in src/core/worspace.c. There are three events :
  WINDOW_ADDED
  WINDOW_REMOVED
  WORKSPACE_SWITCHED

So you'd only need to connect you JS code to these GObject events.


Maybe you can use libwnck else, I guess that's how the old applet works.
