A widget keeps a reference to its parent in self.parent.
So you can just use
self.parent.size or self.parent.pos or whatever.
Depending on what you're doing,
it may be necessary or useful to make sure
you check if self.parent is None first,
so that your code doesn't fail for widgets with no parent.
