Window move at menubar in Gnome

[Andreas Volz <lists brachttal net>]

Hello,

since I installed Ubuntu 10.04 I noticed that I could move windows
while dragging the menubar in Gnome. I like this feature. But I don't
use Gnome, but Enlightenment 17. I would like to implement support for
this feature in E17, but I don't know which calls are behind this on X
level. I tried to find some documentation about it, but failed. Before
I start to dig into Gtk+ code I hope someone on this list could answer
this question.

regards
        Andreas
