Iwidgets problems

hi, I am want to make a widget to represents values stored in an xml file,
following its hierarchised structure. To do so I used widgets from the
Iwidgets package, and pack them up

scrolledframe
    collapsablewidget (from iwidgets/incoming/collapsablewidget.tcl in
sourceforge repository)
        ...some other widgets
        collapsable widget .. and so on

my problem is that I would like to make the collabsable widgets expand and
fill all the width of the chilsite of the scrolled frame.
so far anything I've been trying worked (either the scrollbar disapear, the
background of the frame doesn't refresh, the width of the collapsabe widget
doesnt go bigger than the width of its content.

is there a trick or an impossiblity I don't know ?

I am pulling my hair off !!!

thanks
