[maemo-developers] Dragging rows in a TreeView

[From: Zachary Goldberg]

Hello!

I'm working on an application where I would like the user to have the
ability to reorder the rows of a TreeView.  In my desktop version of
the application I have the user select a row and then hit an "up" or
"down" button.  I figure it would be much more user friendly if the
user could simply drag the rows for maemo.  I have done:

treeview.set_reorderable(True)

Which seems to have had no effect.  I have tried those both in and not
in a hildon PannableArea.

I very much appreciate any advice you can offer,
Cheers,
-Zach
