I'm not sure I understand: once you set a "size policy" to "fixed", it 
seems that you would need to set a fixed size (for a button, for instance).

Or, if you set it as percentage of the original dialog size, still, the 
dialog would need to have an original fixed size, which is about the 
same thing. Or, am I  missing something?

(question aside: can you choose the "size policy" for each dimension 
like, left,top,width,height, or for the whole widget?)

Best,
John
