Making Qt Widgets Stretch and Scale w/ Main Window

Question

I'm wondering if there is a way to make Qt widgets within a QMainWindow widget stretch and scale as the size of the main window is stretched and shrunk. Basically, I'd like the entire window and it's contents to have the same appearance except for size:

At the only way I can think to accomplish this is to get the size of the main window, do the math for every single widget, and reset their sizes any time the main window size is changed, but I'm thinking there's an easier way.

I like this video tutorial on youtube. I'll help you create a layout using QLayout classes. If you use QtCreator/Designer, you can also take a look at the auto-generated ui_MainWindow.XXX file that will clue you in on how it uses some of the UI classes.

As always, QtCreator/Designer has a bunch of hints and tips so you should be able to dig up from the documentation that's embedded in the application.
