Thanks for your answer.
The items are filled. Actually the column which i drag has the same
content as all the other columns.
But I need to send MOTION_NOTIFYs while dragging to the other items.

I believe the standard (gtk) way of passing events only to parents is
not useful for the canvas where elements can be moved around and thus
can be moved 'above' different objects which are not their parent.

parent should be handled more abstract for the canvas.
Maybe a definition:
parent='objects lying underneath an item' or
       'having the same x/y-coordinates'
is miore appropriate.

But I guess that this is not easy ;)

Any idea ?
Any quick&dirty solution for my specific case ?
