[Gtk-sharp-list] Painting on the back of a TreeView

[Iggy]

I wasn't aware that the TreeView had multiple GdkWindows but when I
changed it to BinWindow it worked perfect. Thanks! Heres the code for
anyone who's interested:

<code>
            this.ExposeEvent += delegate {
                if (((exTreeStore)myTreeView.Model).Count == 0) {
                    layout = new Pango.Layout(myTreeView.PangoContext);
                    layout.SetText("There are no results.");
                    layout.FontDescription =
Pango.FontDescription.FromString("Arial 10");

myTreeView.BinWindow.DrawLayout(myTreeView.Style.TextGC(StateType.Normal),
5, 5, layout);
                }
            };
</code>
