[PyQt] How to get index of splitter

[Russell Valentine]

Frans,

I believe before show is called no sizes are figured out of any of the
widgets, unless they were set manually.

I think it'll try to do it's best to comply with all the widgets current
size policies. Usually whatever policy is default is good enough for me,
only once in a while do I change it, I'm not a policy pro. If you want
to know more I'd play around with size policies. The polcies of the
TabWidget, the splitter, and the widgets in the splitter.
