Re: [gtkmm] Treeview: selection and color

[Arnaud Ligot <spyroux spyroux be>]

hum...

I have read all of your documentation but each time, you could only get
the number of the row that is selected not the column number :-/ or
there is something I haven't understand :-)

I have more than one column that must be "editable" so I have to know
the number of the line AND the number of the column where the user
cliched 


thanks

Arnaud
