[Qt-interest] Resizing a window

[Chris Bruner]

I'm trying to do something that I'm sure is simple but somehow escapes
me. I've got a QGraphicsView inside a QFrame inside a QGridLayout inside
a QVBoxLayout inside a QWidget inside a QMainWindow.
I want to resize the window and have the QGraphicsView follow along.
Instead what I see is the window resizing and the view staying the same
and getting covered up.

It looks to me like the widgets will resize themselves when the layout 
changes size,
but I still can't get the layout/widget to change size as the window
changes size. All that happens is the window cuts off the widget.  What
am I missing?

TIA
