[PyQt] Unable to create the C++ code
Hi I am trying to fix the Debian package of PyQwt5 where I get the error: Generating the C++ source for the qt module... sip: QApplication has ctors with the same Python signature Error: Unable to create the C++ code. I do in fact get the same error when I try to compile the PyQt3-3.17.4 sources but PyQt3-3.17.6 compiles without problems. I tried to take a look at the difference between these sources but did not become any wiser. If someone could point out the relevant difference, the same solution might be applicable to PyQwt5. The sip version is 4.7.9. Thanks Gudjon ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] multiple QThread simultaneously
I don't see why there would be a limit. Can you post a sample code?

[PyQt] Problem with latest PyQt build - ImportError: DLL load failed: Invalid access to memory location.
>>> from PyQt4 import QtCore Traceback (most recent call last): File "", line 1, in ImportError: DLL load failed: Invalid access to memory location. If I use the nightly build from 4252009, it all works as intended. Using Qt 4.51 with the included mingw32 to build PyQt. It builds fine and theres no errors, but Python fails to import the *.pyd files. -- View this message in context: http://www.nabble.com/Problem-with-latest-PyQt-build---ImportError%3A-DLL-load-failed%3A-Invalid-access-to-memory-location.-tp23302281p23302281.html Sent from the PyQt mailing list archive at Nabble.com. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] Why does QApplication.processEvents() increase performance?
My Guess is that the time is spent on creating large object events queues that then get processed all at once. In the second approach the queues are smaller and the object could be reused without being created again. just guessing though ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Excellent Phil~ After this patch(against snapshot-0428), the demo is perfect
except the Assistant issue...
