Gtk2 - TreeView style


in Gtk2 the old CTree's line_style and expander_style are gone. But I 
don't like the defaults (no lines and the triangle expanders).

There are a few style properties, but they are read-only, so I can't 
modify them to fit my needs.

Is changing the style of a TreeView in the scope of themes only? Or is 
there any simple possibility to change such things from my application.
