I thnk you just need to overload sizeHint or something in that
category in the Python widget itself.

I would think you'd have to "lift" the signals/slots from the
child widget to the parent in something like FileChooser, but in
the Python widget as is already done in this case:
I'm not sure how to handle the child widgets' signals. Probably
self.connect (self.lineEdit, SIGNAL ("textChanged (const
def textChanged (self, s):
self.emit (PYSIGNAL ("textChanged"), (s, ))
But I would think any "compound" widget will have to do the same
thing, and in C++ or Python. For example, QListView doesn't
expose it's viewport widget in QtDesigner.
As you say though, some of that probably depends on how the meta
object stuff is implemented.

I don't maintain any kind of CVS. I'll post a copy sometime today
- I'd like to look over what I did as I did it kind of quickly
last night, and I have to get some stuff done outside today
(it's snowing and I have to do a few things in case the snow
accumulates and doesn't melt). I'll get a copy posted sometime
today in any case.
