[Qt-interest] setSizePolicy has no effect in subclass of QDialog

Hello Stephen,

what I mean is the following:

every control inside a layout has to exactly tell how it wishes to be
arranged. And this is achieved via size policies.

I think that here you *statically* restricted the maximum size (or
minimum size respectively). Does your dialog really properly react now
if one of your sub controls changes in size (e.g. due to a font change)?

And, by the way, wouldn't it be better to use QLayout::minimumSize ()
instead ?
