      The sizeHint of the created QLayoutItem in a QLayoutBox is incorrect if the parent widget of the layout is already visible (show has already been called). This in turn causes the sizeHint of the QLayoutBox itself to be invalid. At some point they correct themselves, but if you need the size immediately (as I do) it doesn't work.

      No workaround is known.

      The attached code demonstrates the issue (compare with/without the "show" line).
