sizeGroup in a table...

[z pekar gmail com]

Hi,
I have problems packing widgets into a table using sizeGroup. Here I
try to pack 2 gtkRulers around a scrolled window, so that rulers cover
only scrolled window's container and not the scrollbars (like in
gimp), I try to achieve this by putting rulers in the same sizeGroup
with scrolled window's container. But it doesn't seem to work -
instead rulers "cover" also the scrollbars :( what do I do wrong?

here is how it looks like:

and here is how I would like it to be (gimp):
http://img26.picoodle.com/img/img26/3/11/17/f_gimpm_582c25a.png
(pay attention on top-right/bottom-left corners)

I struggle with it for several days already without progress :(

thank you in advance
