[pygtk] Activating the text cursor in a GtkComboBoxEntry

[Thierry Lam]

I have a ComboBoxEntry with a pull down menu represented by a small down
arrow on the right hand side of the Entry widget. Each time I select
something from the drop down menu, the text cursor is not shown in the
Entry widget. Is there a way to activate this text cursor in the Entry
widget?

Thanks
Thierry
