Gtk::TreeView question

[Surya Kiran Gullapalli <skg fluent co in>]

Hi all,
I'd like to create a TreeView, with list store as its model.
The problem is for the column record, where the number of columns will be decided only at run time. Any tips on going about this would be greatly helpful.

Also the problem gets much more complicated, when i've to create some columns, where the type of variables the column should show (like string, bool) will only be decided at runtime.

Any Ideas?
Thanks in advance,
Surya
