Tree view's 'row-activated' will send the path and column as arguments
to the callback. With 'cursor-changed' you just need to call
gtk.TreeView.get_cursor to find out the path and column. With
gtk.Widget's 'button-press-event' you get the event as an argument for
the callback and you just need to call gtk.TreeView.get_path_at_pos with
event.x and event.y to get the path and column.

I don't know if that's easier than some alternative, but it's no more
than two or three lines of code in a callback. I vaguely remember using
gtk.GenericCellRenderer being difficult and there's a good chance of
breakage with new versions of GTK+ if you have to write the rendering
etc. code yourself -- I stumbled on this a couple times. Can you get the
'on-activate' signal if you subclass gtk.CellRendererPixbuf?
