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.
