[pygtk] gtk.ComboBoxEntry not recognized as a GtkCellEditable

[Ruben Lopez]

Hi,

I'm doing my own CellRenderer (derived from GenericCellRenderer) =

following the decorator design pattern, to use an existing renderer and =

add some extra graphics to it, and modify the original renderer =

behaviour in some cases. It's working pretty well with CellRendererText =

and CellRendererToggle as the decorated item, but it fails with =

CellRendererCombo because of something that seems a bug to me:

This is the object that the original renderer start_editing method gives:
    Object: <gtk.ComboBoxEntry object (GtkComboBoxEntry) at 0xb7c3ccd4>

These are the interfaces supported by this object:
    Interfaces: [<GType AtkImplementorIface (159548008)>, <GType =

GtkCellLayout (159763248)>, <GType GtkCellEditable (159768856)>]

This is what happens when I return this object on my custom =

on_start_editing method:
    ** (test.py:23800): WARNING **: return of start_editing() was not a =

GtkCellEditable

I attach the python file where I'm testing these ideas. Is there =

something wrong with my decorator or is this a bug of pyGTK 2.8?

The test file is not adding extra behaviour to the original renderer, =

and it even doesn't show any column data. It's just a proof of concept. =

If you change the decorator with the decorated in the column, the combo =

selector works well.

Thanks in advance.
