No, that code works, as it uses libglade - no creation of liststore etc.
inside Glade. object maps to gobject.TYPE_OBJECT in pygtk.

When I use gtkbuilder, and create liststore etc inside glade, I only
have this in my constructor, related to the treeview:


showsStore = self.builder.get_object("showsStore")

for Show in database :
    showsStore.append([ Show.name, Show ])

I get the error when appending to showsStore - the ListStore.

The problem is, I don't know how to handle the treeviewcolumn /
cellrenderer for the object.

Yes, it is a Python class.

It is what I use with libglade, and it works if I create a treeview/liststore/treeviewcolumn/cellrenderer without the object.

The pyGTK reference for ListStore -> append() http://www.pygtk.org/docs/pygtk/class-gtkliststore.html#method-gtkliststore--append
