[pygtk] Re: Icon in TreeStore... continued

[Muhammad Ali]

Hi again,

I am trying this example from the faq:
http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq13.014.htp

*******************************************************************************
 folder = gtk.gdk.pixbuf_new_from_file('folder.png')
 folder_open = gtk.gdk.pixbuf_new_from_file('folder-open.png')
 def init_model(self):       
        store = gtk.TreeStore(gtk.gdk.Pixbuf, gtk.gdk.Pixbuf, str)
        # Fill the model with some silly sample data.             
        for p in xrange(10):
            parent = store.append(None, (MyTree.folder, MyTree.folder_open,
                                         'Parent %s' % p))
            for c in xrange(5):
                store.append(parent, (MyTree.folder,
MyTree.folder_open, 'Child %s' % c))
        self.set_model(store)

   def init_view_columns(self):            
        col = gtk.TreeViewColumn()
        col.set_title('Silly Example')
        render_pixbuf = gtk.CellRendererPixbuf()
        col.pack_start(render_pixbuf, expand=False)
        col.add_attribute(render_pixbuf, 'pixbuf-expander-closed', 0)
        col.add_attribute(render_pixbuf, 'pixbuf-expander-open', 1)
        render_text = gtk.CellRendererText()
        col.pack_start(render_text, expand=True)
        col.add_attribute(render_text, 'text', 2)
        self.append_column(col)
*******************************************************************************

When i run this, only the icons for the parent appear. They do not
appear for the children. Furthermore, if i try to add something after
i make an object like:

*******************************************************************************
tr = MyTree()
store = tr.get_model()
parent = store.append(None, (MyTree.folder, MyTree.folder,'outside'))
*******************************************************************************
The new node is added but without the icon.

Why don't the children show their icon? and Why does the 'outside'
node added later has the icon missing?

Thanks,
Ali
