Re: [gtkmm] TreeView/ListStore

Thank you, but doesn't that change the colour of the whole column? I 
need to change the colour of a whole row. As far as I understand a 
CellRenderer is related to how a column is rendered in all the rows, am 
I right? How to change that behaviour for a particular row? What I'm 
trying to achieve is one row in red and the next in blue, for example.
