When you say "can I just peek" and that "I" means you personally, yes. As a
human being and an engineer with a decent knowledge of software development,
you'll be able to guess the semantics of some of the methods and their
arguments based on their names alone.
But for that you don't strictly need the X window properties: the QWidget
interface above already exposes the winId, so you can map one to the other
manually.
If the "I" in "can I just peek" were a software, then you need a standard
interface, with standardised methods and behaviour so that one application can
communicate with another. That's what I am asking for: do we want to define
some interfaces?
