drag and drop between a GtkTreeView and a GtkLabel

[phytOS <phytos altern org>]

Hi everybody,
I want to drag and drop a element of my GtkTreeView on a label to have
the text diplayed in the selected element on my label. I read some Gtk
tutorial and the API on gtk.org but my program do not work.
I can see the drag_data_get and drag_end signals but not the
drag_data_received...
So, i hope someone can help me here because i'm really blocked by this
little problem...

Thanks for your help,
phytOS.
