[PyQt] PyQt4 import module fails second time when running python from Qt-C++ based shell
Hi, I've attached a small Qt project for a Python shell. It also uses QScintilla. It's amazing that I made this in about 5 minutes, thanks Phil! The problem I'm encountering is that I can only correctly import a PyQt4 module once using this shell. If I try to import again then I cannot use classes within the module. The code from PyQt4 import QtCore QtCore.QObject() succeeds the first time it is run. The second time it complains that "AttributeError: 'module' object has no attribute 'QObject'". This does not happen with other modules like sys. The Python execution code uses all temporary variables. At first I thought this was because of a flaw in my C++ code, but the success of loading a non-Qt-based modules piqued my curiosity. Has anyone ever seen something like this? sample.tar.gz Description: application/compressed-tar ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

No idea, but have you checked:
- QDir.currentPath()
- prepending ./
- using Qt's resource system

[PyQt] StyleSheet relative path
Hi
Lets say I have a styleheet and an image file in the same folder
QTextEdit, QListView {
background-color: white;
background-image: url(myImage.png);
background-attachment: scroll;
}
I expected this to work since they are at the same level but I still
have to type the whole path like so:
QTextEdit, QListView {
background-color: white;
background-image: url(/path/to/my/file/myImage.png);
background-attachment: scroll;
}
What would be the correct syntax to make the filename relative to the
stylesheet so that the image will load on any machine no matter the root
path
Thanks

Which version of PyQt?
Can you send .ui file that demonstrates the problem?

[PyQt] a unhandled case uiparser.py:createSpacer
Hi there!
Today I used the qt designer, added some spacers to centre some knobs.
I wanted to reduce/reset the sizeHint of the spacers, so I pressed the
reset button right of the value field, which resets the sizeHint
property to 0x0, that's perfectly what I want. So I saved the .ui file
and started my application:
[...]
File "/usr/lib/pymodules/python2.6/PyQt4/uic/uiparser.py", line 308, in
createSpacer
width = int(elem.findtext("property/size/width"))
TypeError: int() argument must be a string or a number, not 'NoneType'
Setting the sizeHint to 1x1 works fine. - The designer sets by default a
non-zero value.
The code in createSpacer assumes the presence of width and hight
parameters, which is fatal in this case.
(I didn't dig into the definition of the .ui file, to see whether its
format requires the presence, at least the qt documentation does not
forbid 0x0 spacer dimensions.)
Cheers, Achim

I use the latest PyQt and SIP snapshots. You need to provide a minimal runnable example, and describe the procedure to provoke the failure. Don't forget to mention your environment, and paste in python and gdb tracebacks. Pete ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
