Re: [PyQt] Question on QTreeView, interactive expanding/collapsing
Am 19.04.2011 23:29, schrieb Zoltan Szalai: The "*" key expands all children but you can easily implement your own expand / collapse subtree functionality. Wow, I didn't know about that! But Qt needs a method to expand all subchildren recursively. Why is this method not available? Or is it? Background story: I've needed an expand_all_below action. I've implemented this similiar to what Paul suggested (a bit more rookie-like with recursion), but wasn't so happy with the performance on very large trees. So my hope is that the method used by Qt internaly must be a faster. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Kudos
Hey Phil, I recently built some Python bindings (using Cython) for a 3rd party library that had to be built using Visual Studio 2005. Its great having these bindings and being able to use Python. Unfortunately, to install any other Python modules I have to build them myself as nobody offers versions using Visual Studio. When I wanted to start using Qt from Python I initially chose PySide for its more liberal license and because as of their 1.0 release they had Windows support. Building it was an absolute pain. I had to fix some scripts here and there. The resulting install didn't even have uic and I was instructed to copy it from the official binary release of the PySide Windows installer. After doing this it wouldn't compile my .ui files and just error out. I compiled the .ui files using the PyQt pyuic4 and got PySide to work okay. Because of all those problems I decided to give PyQt a go on Windows. Sip installed no problem. PyQt gave me some trouble using "configure.py" because I had a space the path of the source directory that I was running configure from. After moving it to a more boring "C:\PyQt-win-gpl-4.8.3" it installed just fine. I wound up having a problem with pyuic4 also just like I did with PySide. I dug into it a bit and it was a case of me not having built the pyexpat module. After building it and putting pyexpat.pyd in the DLLs folder pyuic4 worked just fine. Makes me wonder if thats what PySide was missing as well. In any case, for now I'll be using PyQt. One thing that PySide did nice that PyQt didn't do was get the Qt dll files copied into the the Python installation so that everything was self contained. It would be nice not to have to have end user's of my programs have to do a full Qt install when they'll only be using it from PyQt. Anyway, just wanted to say kudos to having a relatively pain free installation experience on Windows (with Visual Studio 2005 anyway) compared to the "competition".

I don't believe, that this is possible without getting very, very dirty, but if you found a solution, let us know. (ld preloading comes to my mind).

[PyQt] Reopening QT Window - Segfault
Hello I need some help to implement a QT Window to draw some OpenGL in an python-GTK2 application. In the GTK application, I have a push button which will launch an OpenGL scenery (In a QT window). I should be able to close the OpenGL Window and to reopen it as many times as I want, without exiting the GTK application. I used the code found here : http://www.siafoo.net/snippet/316 , but rewritten for my app (as I call main() from the GTK part) : def main(): app = QtGui.QApplication(['Spiral Widget Demo']) window = SpiralWidgetDemo() window.show() app.exec_() My code works perfectly under Mac OS X with python 2.7 and the pyQT port from macports. But under Ubuntu 10.10 with python 2.6.6 I get a segmentation fault if I try to reopen the window. What I do : - Open OpenGL Window (QT) - Close it with the X - Reopen it - SegFault here Why is there a difference between the OS X and ubuntu packages ? I have a backtrace (made with dgb) of the segfault. It seems that the memory is not cleared when I close the window. I don't want to use sys.exit because it will also close my GTK app. #0 0x00497d72 in ?? () #1 0x00499642 in PyErr_WarnEx () #2 0x7536d274 in ??

Right. Sorry, my bad for not reading your first response correctly.
Anyway, I hope some poor souls will find this thread via Google when
they run into the same surprise.

The behaviour *is* the standard Python behaviour - it's not a PyQt thing.
Change "QtCore.QObject" with "object" and add a __getattr__ method that
raises an exception and you'll see.
