[pygtk] liststore using glade3, gtkbuilder, and the glade designer

[Stephen George]

Hi Jon

Have you added any renderers to the treeview cell?

A snippet of my program where I had the same problem (empty lines) with 
a combo box until I added the renderer

        self.builder = gtk.Builder()
        self.builder.add_from_file('app.glade')
        self.window = self.builder.get_object('scanapp')
        self.window.set_size_request(1000, 800)
        self.builder.connect_signals(self)
        cell = gtk.CellRendererText()
        self.combobox = self.builder.get_object('ScanTypeCombo')
        self.combobox.pack_start(cell, True)
        self.combobox.add_attribute(cell, 'text', 0)

You need to tell the listview how to render the cell (it could be an 
image, or text), and I couldn't work out how to do that within Glade, so 
I did it in the initialisation code for my application.
You will need a cell renderer for each column in your treeview.
I haven't done a treeview/liststore with gtk.Builder yet.

pygtk-demo has a good example of how you program it yourself  (not using 
glade designer)
