:-) There should be a post from me, answering to my own mail when you
read this. Unfortunately I was without network in the meantime. I
changed QObject to QWidget and also cc'ed Phil so it'll hopefully get
into the next snapshot he releases..

You probably missed that this is from porting a C++ application of mine
to python so that I have it in the same language as the HTML-Parser I'm
going to use. Thus, the .ui files were created by using a
custom-widget-library for qt designer. When I started porting, I just
copied over the .ui's made pyuic4 generate code that I can work with and
now all I have to do is reimplement the widget classes in Python and use
the Ui_<blah> from there. Works pretty well so far.

Didn't read that as I have no idea about all this metaclass/type-stuff
from python which you're using.

>From what I have understood and from what I saw, all this proxy-objects
stuff is pretty good in writing the same thing with less code. If you
compare your uic to the one shipped with Qt4.1 just by lines of code you
decreased it from 15000 to 1113. Though there may be more stuff that the
real uic does.
You will soon meet a person who will play an important role in your life.
