[Gtk-sharp-list] TreeModel

[Maciej Piechotka]

Implemented TreeModel interface would make my application simpler.
I've read GTK+ 2.0 Tree View Tutorial
However:
1. To implemented in C I need overload 14 functions. In C# I have to
overload 41(!). Some of them(27) was probable implemented in
GtkTreeModel
2. I don't know how get the new GType.

I was thinking about:
1.  C++/CLI - but there are no plug-in for {Sharp,Mono}Develop
2. Some additional native library (dll/so), but it wouldn't be easy to
move through the platform and I don't know how to import function from
library. Moreover I need to access from Model to C# objects (in other
case I'd implemented all in C/C++).

How *should* I implemented TreeModel in C#?
Is it possible?

Best regards.
