[pygtk] Can't get tool tip to display

[Gerald Britton]

Hi Dieter,

I just realized that your sample code displays a tooltip per row.
What I would like to do is display the tip per column.  So, if I'm in
column 3, I see "In column 3" or whatever, regardless of the row.  How
should I modify your sample code to do that?
