[gtkmm] editable cells

[Martin Wackenhut <Martin Wackenhut it-dv-wackenhut de>]

Hi,

I want to use an editable bool in my TreeViewModel.
This all works fine now I only would like to be able to set this bool under
certain conditions(If a checkbox somewhere else is activated).

The tutorials tells me something like
"Use the append and insert method, then connect to the cell renderer".

I completely don't understand what to do whith this. I thought when I
append or insert a column I would just expand my list.

Does anyone have a short example on how to do stuff like this?


Thanks

Martin
