Re: [PyQt] ANN: PyQt v4.9.2 and SIP v4.13.3 Released
I find that with PyQt 4.9.2 and SIP 4.13.2 or 4.13.3 calls to QMainWindow::saveState freeze in *some* circumstances. Reverting to PyQt 4.9.1 fixes the issue. The freezes are happening in a closeEvent handler (linux 64bit, Qt 4.8.2, compiled from source packages). I haven't been able to figure out exactly when or produce a simple test case. But I thought I should document the problem in case other people experience it. Kovid. On Thu, Jun 21, 2012 at 03:21:21PM +0100, Phil Thompson wrote: PyQt v4.9.2 and SIP v4.13.3 have been released.

It can. I thought it would be more correct to extend configure, but if you'd
rather not I can just CXXFLAGS=${CXXFLAGS} ${CPPFLAGS}. That's why I sent
you the patch for review before applying it to Debian.

[PyQt] Issue building PyQt4 4.9.2 on Mac OS X Lion
Hello, I tried to build latest PyQt4 on Mac OS X Lion without success. The command python3 configure.py --verbose gives this output. Determining the layout of your Qt installation... /usr/bin/qmake -spec default -o qtdirs.mk qtdirs.pro Error: /usr/bin/qmake failed to create a makefile. Make sure you have a working Qt v4 qmake on your PATH or use the -q argument to explicitly specify a working Qt v4 qmake. The same command works fine for PyQt4 4.9.1. Any help is appreciated.

[PyQt] Combo box very slow for Thai language data.
Hi Sorry if I use wrong English. I found that the combo box with drop down list will be very slow when click the combo box, the drop down list need a few second to show if the data on the list was Thai language. But the English data was no problem. This problem occur after PyQt version 4.8.6. I use 64 bits windows 7, python 3.2.3, eric5 5.2.3 with database mysql 5.

I figured out the problem. It is a conversion from QByteArray to
bytearray. The following code causes a hang:
bytearray(self.saveState(1))
This does not:
self.saveState(1)
Attached test case.

Just for completeness, here is the simplest possible test case: python -c from PyQt4.Qt import QByteArray; bytearray(QByteArray(b'')) This causes a hang with PyQt 4.8.2 but not with PyQt 4.8.1 (sip 4.13.3) Kovid.
