Re: Using XDnD in extensions

[Joakim Soderlund <joakim soderlund gmail com>]

Hello!

Seeing as what I wanted to do wasn't possible I created a patch which
extends the XDnD support in GNOME Shell. The patch allows for actors
to accept XDnD drops and retrieve information about them. You can find
the patch along with a simple extension demonstrating its usage at the
following URL:

http://jocketf.se/files/xdnd/

The patch and extension was written for GNOME Shell 3.6.2. If there is
any interest in this I can try to make it work for the Git master as
well.
