Re: Gtk::CellRendererCombo how to

[Pavlo Solntsev <p_solntsev meta ua>]

Thank you so much, Phil.

I didn't realized I have to insert ListStore model as value for each
row. Also, a little bit confusing was part render->property_editable()
= true. I see logic here now, but it wasn't clear. 

Surprisingly, I wasn't able to locate this example on the web site.

Thanks again.

-Pavlo.
