[PyQt] newbie questions...
Hey All, Apologies for the newbie questions, I'm still trying to decide what gui toolkit I want to use and so would like to give Qt4 a go. Everything I do is in python, so that leads me to PyQt4 ;-) I'm currently doing entirely open soruce development on Windows. However, I wouldn't like to rule out developing some commercial apps later. What's the licensing position on this? This, from the Trolltech website was more than a little weird: The Commercial License does not allow you to incorporate code developed with the Open Source Editions of Trolltech software into a proprietary project That seems weird to put it politely. I would have thought they both had the same interfaces? Anyway, some questions: - where do I get the Qt Designer from? - how come PyQt4 isn't on PyPI? (Nowadays I'm used to just specifying packages as egg requirements in a buildout.cfg (http://buildout.zope.org/) but I guess I can't do that with PyQt4?) thanks for any help!

[PyQt] PyQt shadowing virtual slots?
I encountered a strange problem when wrapping a custom QDialog subclass. This subclass implements accept and connects it to QDialogButtonBox::accepted, but this would not get invoked and I could not for the life of me understand why. Eventually I discovered that the reason was that I did not declare accept among the class' methods in the SIP wrapper. Why is it that C++ reimplementations of slots are hidden if they are not also wrapped in the SIP equivalent?? See attached demo (test.py is the main script).

No.

[PyQt] Installation problem on OSX
Hello everyone, I am new to the list so please correct me if I ask my question in the wrong way. Recently I installed the latest version of Qt (4.4.1) and the latest version of PqQt4 (4.4.2). My python installation is from the scisoft package (ESO software bundle) version 2.5.1. Installation of PqQt4 was done using a simple: sudo python configure.py (seemed to be necessary because without the sudo it complained about: IOError: [Errno 13] Permission denied: 'qtdirs.pro') followed by: sudo make sudo make install This seemed to work. But if I run the following from within python: import sys from PyQt4.QtGui import * I get the following error: Traceback (most recent call last): File stdin, line 1, in module ImportError: dlopen(/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/PyQt4/QtGui.so, 2): Library not loaded: QtGui.framework/Versions/4/QtGui Referenced from: /scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/PyQt4/QtGui.so Reason: image not found At first I thought it might be the `library' with lower case because according to find my installation is located at: /scisoft/i386/Packages/Python-2.5.1/Python.framework/Versions/2.5/lib/python2.5/site-packages/PyQt4 /scisoft/i386/Packages/Python-2.5.1/Python.framework/Versions/2.5/share/sip/PyQt4 /scisoft/i386/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/PyQt4/ So I tried changing `library' to `Library' in pyqtconfig.py and Makefile (after configure.py) but this did not solve the problem.

[PyQt] Strange bug in PyQt
I don't know how to explain it, si I have to use pictures.
Here's how my app looks when things go bad:
http://flickr.com/photos/ralsina/2744179213/
Here's the good:
http://flickr.com/photos/ralsina/2744178603/
What's the difference in the code? This:
In the good version, I create the star icon for each item:
item1.setIcon(QtGui.QIcon(':/star.svg'))
In the bad version, I created a global:
star=QtGui.QIcon(':/star.svg')
And used it instead:
item1.setIcon(star)
I had the same thing happen to another app before and never figured out why it
happened.
I am using
qt 4.4.0
pyqt 4.4.2
python 2.5.2
On Linux.
Any ideas?

It's in the module's scope so it shouldn't be deleted while the module is
