[Gtk-sharp-list] Treeview iteration

I'm sorry I really don't follow this code sample.  I've been trying to
work with it for a few days and I'm racking my brain bigtime.  Why can't
this stuff be a collection of nodes or something?  A simple recursive
method with a for loop would be so much easier, looks like you have
methods to iterate next, check if theirs children etc.

I'm starting to think the others asking for more C# integration may be
right.  I find it much more appealing to do something like this:

Mytreeview.Nodes - a collection of root nodes
Mytreeview.Nodes[0].Childnodes - a collection of child nodes
MyTreeview.Nodes[0].Childnodes[0].Childnodes - etc etc big tree of nodes

Other properties that would be helpful is like .HasChildren, etc.  I
don't know, I hate to complain like this, I really feel bad, but I feel
the learning curve on this stuff when you don't have any GTK background
pretty tough.  I just want to loop through the freaking nodes! Lol

On another note, has anyone taken a look at my post about the
glade-sharp problems on win32 via .NET framework?  I haven't seen any
responses at all.

Take care,

I do this in nunit-gtk:

	void GrayOut (TreeIter iter)
		SetValue (iter, 0, grayCircle);
		TreeIter child;
		if (!IterChildren (out child, iter))
		do {
			GrayOut (child);
		} while (IterNext (out child));

If the 'iter' parameter is the first node, this method traverses all of
its childrens.
