Anyhow, I don't think, that cProfile is the proper instrumentation for
that kind of issue, since PyQt is throughoutly compiled code, you
should cope with that, and do proper profiling
I'm hoping there is a PyQt historian out there that can answer this
question for me.
We have a major application that we've been unable to use anything
beyond Pyqt 4.3 due to what I think is a performance issue with
setVisible. I'd like to give an example but this is proprietary code
and
I wish. I can put in a request to do so, but, its often a long process
to get legal approval.

Currently I'm running the latest PyQT 4.3 snapshot with the offical 4.3
release of Sip and Qt 4.3.1, although the problem is still there with
PyQt 4.3 official release.
What I have is a QWidget which is basically my own type of progress bar
embedded in a QTreeWidgetItem.
progressBar = jobPro
Is it possible to have maybe some unsupported commercial license
snapshots made available? Once a commercial release is out, we're
pretty much stuck with it while bugs are fixed in the snapshots.
