Re: Removing/Reordering Multiple Selections in GtkTreeModel

[Jared Krinke <furiousj u washington edu>]

So, uh, did you take a look at the link? I eventually figured out that
gtk_tree_selection_get_selected_rows() was the key and got it all
working. I was posting so that if people search the mailing list, they
can find an explanation of how I did it. But thanks for verifying that I
was on the right track.

Yes, deleting backwards works in a GtkListStore (and I think there
should be some simpler API to allow this--one without tons of lists,
like maybe a gtk_selection_foreach_reverse), but for GtkTreeStores, I'm
guessing that's not really possible.
