[gtkmm] Treeview question

[Daniel <dss home se>]

Hello!

I'm working on a class using the treeview to display its data. I have studied the treeview/treestore example (gtk-demo) and it has been very helpful. However, in the example (treestore) there are also "toggle-cells" on the rows that you can expand...for example on the january row there are also some "toggle-cells". In my program I would like the row to be empty after the text-cell "january"... 

Simple solution?

Complex solution?
