I've got some code in a class that extends gtk.TreeView, and this is the init method. I want to create a tree view that has 3 columns. A toggle button, a label, and a drop down box that the user can type stuff into. The code below works, except that the toggle button doesn't react to mouse clicks and the label and the ComboEntry aren't drawn. (So I guess you can say it doesn't work). I can add rows just fine however.

    #make storage                   enable/disable  label    user entry
    self.tv_store = gtk.TreeStore(gtk.ToggleButton, str, gtk.ComboBoxEntry)
    #make widget
    gtk.TreeView.__init__(self, self.tv_store)
    #make renderers
    self.buttonRenderer = gtk.CellRendererToggle()
    self.labelRenderer = gtk.CellRendererText()
    self.entryRenderer = gtk.CellRendererCombo()
    #make columns

    self.columnButton = gtk.TreeViewColumn('Enabled')
    self.columnButton.pack_start(self.buttonRenderer, False)
    self.columnLabel = gtk.TreeViewColumn('Label')
    self.columnLabel.pack_start(self.labelRenderer, False)
    self.columnEntry = gtk.TreeViewColumn('Data')
    self.columnEntry.pack_start(self.entryRenderer, True)

    self.append_column(self.columnButton)
    self.append_column(self.columnLabel)
    self.append_column(self.columnEntry)

    self.tmpButton = gtk.ToggleButton('example')
    self.tmpCombo = gtk.ComboBoxEntry(None)
    self.tv_store.insert(None, 0, [self.tmpButton, 'example label', self.tmpCombo])

thanks.
