For what it's worth, I've got SelectedForeach to be useful in the following way...

Create your own GetAllSelected() function in a convenient place, (my class encapsulates a scrolled window and TreeView).

Have a member variable in your class that's an ArrayList called 'rows'.

Your GetAllSelected does something like:

        public IList GetAllSelected()
        {
                TreeSelection selectionInfo = widget.Selection;

                rows = new ArrayList();
                selectionInfo.SelectedForeach(new TreeSelectionForeachFunc(recordRow));
                Console.WriteLine("got " + rows.Count + " rows");
                return rows;
        }

And the recordRow() function is something like this:

        private void recordRow(Gtk.TreeModel model, Gtk.TreePath path, Gtk.TreeIter iter)
        {
                string listIndex = path.ToString();
		// Optionally look up some data based on the fact that
		// list index tells you which row is selected
		rows.Add(listIndex);
	}

Then when you call your GetAllSelected() function you have full control over what gets returned.

I realize it's far from a one-liner, but I think it gives you all the control you could want...

Hope that helps!
