Sorry for asking questions, instead of answering them...

(By the way, my questions are not meant in any way to cast doubt on what you're
doing -- it's just me trying to learn something here.)

Could you explain a little more the technique you're using here, and what its
purpose is?  What does this buy you?  Is this a technique I should try to learn?

How do you "morph" a QHBoxLayout into a QWidget?   QHBoxLayout doesn't
derive from QWidget, and I _think_ the closest common ancestor of the two is
QObject.

Do I assume correctly that your UI file is produced by Qt designer?

Is MasterWindow a QDialog?

Is the question how to make mainLayout the central "widget" of MasterWindow
in Qt designer, or in code (or either way)?

Sorry for all the questions...  Just trying to learn some of the
tricks of the trade.
