[Qt-interest] QWizardPage fields registered globally?

Hi Zack,
Without seeing your code, I'd say the simplest solution is to
reimplement isComplete() for each of your wizard page classes and be
sure any input changes emit completeChanged(). It's a smidgen more work
to code up input validation instead of relying on mandatory fields but
it probably will offer more flexibility.
