Re: Adding Diffrent Gtk::CellRenderer in different rows of same column in Gtk::TreeView

["Andrew E. Makeev" <andrew solvo ru>]

Making custom cellrenderer is a good idea. But you won't need to use
GTK(MM) renderers, you should calculate widget allocation and draw cell
area all inside your custom class ("make it from scrap").

Look at sources of renderers you would to use (GTK) and implement their
code in your custom renderer (with GTKMM functions).

I have custom class that could draw text, numbers and datetime, even
more, when user would to edit cell it returns appropriate widget (combo,
spin, entry).

I am using Glib::PropertyProxy< void* > property_data_ to store cell
data in my custom model, where I am saving pointer to object that
describe everything I need to draw cell area.
