I'm not sure I understand your situation right, but:
if your panel "knows" at run time that it's size has changed (e.g.
from a method that adds the new widget to it) then it could fire a
change event via DeferrerdCommand. The glass panel could be registered
as a listener with it and obtain new width/height offsets.
