[Gtk-sharp-list] Problem with sorting TreeView.

[Tensai Cirno]

I've got treeview with complex liststore.

Treeview has only 1 column with 2 cellrenderers (pixbuf and text) and
liststore 3 fields (pixbuf, text and internal bool).

I've written SortFunc and set liststore.DefaultSortFunc = SortFunc. What
i should do to perform sorting itself? Not just Ascending/Descending
sort of 1 column, but complex sort with SortFunc.
