Would appreciate some help here.
I don't like how these stacked widgets take up all of this vertical space
when the window is resized.
I have tried setting a size policy to minimum on the stacked widgets but no
luck.

I tried putting a vertical spacer on the bottom yet these stacked widgets
want to take up space when resized.

Any Qt4 help would be appreciated.
Am I cleaning up my tail processes correctly? Is it just the QThreads I'm
screwing up? Are there other hidden dangers with my implementation?

Weird.

I'd like to be able to do something in PyQt that I know how to do in

This must be possible in P

Any help is appreciated.
