Can't be done, but you can get the information before the widget is mapped.
If you set mapped_when_managed to FALSE on a shell widget. I will not be 
mapped when it is realized.  This way you have relize the widget, get its size,
relocated it, and then map it.  This is a bit ugly, but it looks like it will
do what you desire.
