Re: GtkTreeView - drag & drop

["Tadej Borovšak" <tadeboro gmail com>]

Hello.

I'm far from expert at those things, but to achieve simple reordering,
I think it's enough to call gtk_tree_view_set_reorderable on your
GtkTreeView (if you created custom tree store for your treeview, you
need to implement GtkDragSource and the GtkDragDest interfaces in it
to make things work). Using this method also disables all other DND
activities (you cannot drag rows to other widgets).

To implement "copy when Ctrl is pressed" behavior, you'll need to look
at the API for DND. See docs for more info (there is not much info,
but still better than nothing;):
http://library.gnome.org/devel/gtk/stable/gtk-GtkTreeView-drag-and-drop.html

I'll play around a bit and see what can I work out.
