Hmm. Yes it wasn't the cut, paste n' run kind of example, but one that 
would actually require you to do some thinking too.

myModelColumns is supposed to be your TreeModelColumnRecord, and color 
is a column in which you would put the color of each row (a string). But 
you can, of course, replace that right-hand side of that line of code 
with whatever logic you'd like to use to choose the color.

I share your frustration there. As with many parts of gtkmm, this 
mechanism is not very well documented. The GTK+ docs at least has 
something to say about it:

http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeViewColumn.html#GtkTreeCellDataFunc

Sometimes the best source of information is just googling around.
