title: Gtk treeview problems
body: <p>I have a simple treeview (like this one - <a href="http://www.mono-project.com/GtkSharp_TreeView_Tutorial" rel="nofollow">http://www.mono-project.com/GtkSharp_TreeView_Tutorial</a>) filled with 200 items and connected to scrollbar. Everything works, but when I select an item and use arrow keys, selected item can be out of visible area. Is it possible to focus on it or set adjustment of scrollbar, i.e.</p>
  
  <pre><code>void HandleTreeSelectionChanged (object sender, EventArgs e)
  {
      vadjustment.Value=SELECTED-ITEM.DISTANCE-FROM-TOP-OF-TREEVIEW;
  }
  </code></pre>
  
  <p>And one more question: How to paint a black border to table (this tree.EnableGridLines = TreeViewGridLines.Both; makes just inside grid).
  Thanks in advance.
