Yes, the code can be found here:
https://garage.maemo.org/plugins/scmsvn/viewcvs.php/trunk/hildon-extras/hildon-extras/he-fullscreen-button.c?revision=6&root=hildon-extras&view=markup

What you do is, you basically create a new window without decorations
and with transparent background. On that window you draw using Cairo. So
you're not using standard widgets but you paint everything by your self.

The code I linked is a specific implementation for a button which will
let you leave fullscreen mode easily. It's not a generic overlay widget.
It would be nice to have such a widget in hildon-extras, so if you're
writing one, please let me know.

Cheers!
