[PyKDE] Embedded Python problems

[Jan L. Nauta]

Hi,

Qt 3.1.2
Python 2.2.2
Sip/PyQt 3.6
Visual C++ 6.0 SP5

I have a C++ Qt application in which I have embedded Python to provide
external wizards. After upgrading to the above configuration from a really
old configuration (Qt 2.3.2, Python 2.1.3 and ancient Sip/PyQt) the wizards
started crashing constantly. It appears that Python objects aren't destroyed
correctly, probably because there are references from the C++ code still
lingering. i.e. Normally, in C++, I set the parent of a dialog to
qApp.mainWidget(). This crashes horribly in Python, the next time a Python
function is called. If after the dlg.exec_loop() I do a manual
qApp.mainWidget().removeChild(dlg), everything appears normal. Then I
noticed other crashes, with QPainters attached to QWidgets...

To make a long story short: Are there people doing similar things that work
correctly? How do you do that?

Any help, hints, insights, would be greatly appreciated,

Regards, jln
