[gtkmm] TreeView Column Buttons

[darco <darco deepdarc com>]

First off, I apologize if this is a dupe message. My settings on the 
mailing list were off, as I'm in the process of changing email 
addresses.


Is it possible to replace the "Buttons" at the top of each column in a 
Gtk::TreeView with an entirely  different widget? I don't mean just put 
the widget inside of the button... I want the widget to fill the entire 
region, not just what is considered inside of that button.

I wrote a custom time-line CellRenderer which works well, but I'm 
trying to figure out a way to display the what time-region the cell 
covers... A Gtk::HRuler (or similar) widget would be perfect for that 
position, so that I could easily read off the the time.

If I cannot do this, does anyone have and suggestions to implement 
something similar in a TreeView?

Thanks
