Hi,
The GtkWidget / GtkTreeView paradigms dont fit together
that easily, that is by design. GtkTreeView technology is designed
to be efficient to draw a list/tree of items, this way rows in
a treeview dont really take up any resources when they are not
visible (so you can easily have over 5000 items in a treeview without
slowing things down) - GtkWidgets own screen realestate and thus
cannot be packed into a treeview row.
I agree it might be interesting if an unparented GtkWidget could simply be
used as a rubber stamp on some input buffer though...
(practicly speaking though, gtk+ doesnt do this).
Cheers,
-Tristan
