Setting QWidget size

[Rich Shepard]

Looking in my two PyQt5 books and on the Web I'm not seeing how to
successfully set a QWidget main window's size. Test code attached.

The overall application will use a QMainWindow with a QTabWidget. Individual
pages have a QWidget as the container (unless my understanding is flawed).
I've tried to add width and height to the attached testgrid.py and it loads
without error, but as a very small window. My readings and web searches
haven't let me find the proper syntax to set a default initial window size
for each tab's contant to 800x600 (unless they need to be smaller to fit on
the QTabWidget in a QMainWindow.

I've also tried qtc.QSize(800,600) without success.

What's the proper syntax to open the test application at a size of 800x600?

TIA,

Rich
