[Gtk-sharp-list] Overriding Key events in NodeView

[Piotr Zurek]

Hi guys,

In the NodeView, with an editable column, pressing "Enter" causes the 
active cell to enter the editing mode. The same thing happens, when the 
"Space" is pressed. How can I override those events to get them to do 
something else?

The method below doesn't even display the "key" for "Enter" or "Space".

     void outlineView_KeyPressEvent (object o, KeyPressEventArgs args)
     {
         string key = args.Event.Key.ToString();
         Console.WriteLine(key);
     }

And one more quick question. How to get a reference to an 
expanded/collapsed TreeNode in the NodeView? The Gtk.RowCollapsedArgs 
returns reference to TreeIter or TreePath. How do I get those to point 
me to a TreeNode?

Cheers
Piotr
