You have misunderstood.  It is absolutely against The Rules(tm) for a
widget to ignore resize requests from its parent.  Keep this in mind
when trying to unravel the gordian knot of geometry management.

Resize policy controls whether or not the drawing area (or other
sub-class of BulletinBoard) will respond to changes in its children
with geometry requests of its parent.  If resize policy is none, the
widget never makes a request due to changes in its children.  If the 
policy is grow, the widget only makes a request if changes in its 
children cause the drawing area to grow.  If the policy is any, the
drawing area will make a geometry request any time changes in its
children cause the drawing area to have a new optimum size.
