Hi David,
Thanks for considering my question.

Can a qt.conf file be used to specify an images directory using the

Maybe you could use the Data entry for images:
http://doc.trolltech.com/4.5/qt-conf.html
That's exactly what I'd thought, but didn't get positive results.
Though it could be due to incorrect syntax. For example, web
searching turned up the following tip that helped resolve my "cannot
move to target thread error"
Create a file dist/<application.app>/Contents/Resources/qt.conf
with contents as follows:
[Paths]
qt_plugpath=plugins
Is there an analogous term, qt_plugpath, for data directory
declarations? I haven't been able to find a reference to either in
any of the trolltech/nokia doc pages or the Qt Assistant. qt_plugpath
seems to work; but I'd feel more comfortable if I could find an
official reference to it ;)
I wonder if I'm barking up the right tree. My app displays images
that have been compiled as resources (.png, .tif, or .jpg) without
issue on Fedora and Windows. But it doesn't display them on OSX.
(Note that I'm using a qt.conf file in my OSX app bundle to locate a
plugins dir.)
So, I guess you're packaging your application along with Qt and PyQt
in a
bundle and I assume that support for images is built as plugins, and
I'm
guessing that some misconfiguration is causing this to fail.
Yes, though I haven't built any of the support for images explicitly.
Rather I've configured my build machine using macports. The issues I
ran into building for OSX (ironically, the OS I'm developing on)
placed me squarely between three technologies: Qt/PyQt, py2app, and
macports. Finding which of the three was the culprit, or which could
be used to provide a cure, proved a challenging task.
The enum docs (http://doc.trolltech.com/4.4/qlibraryinfo.html) aren't
specific about image data and my tests at possible syntax haven't
yielded any positive results.
The QLibraryInfo class and your resource files are two separate
things - I
assume that by "resources" you mean you compiled your image files to
Python
modules using pyrcc4. Is that the case?
Yes, the images are compiled in a .qrc file.
A solution that seems to be working is copying the tiff and jpg
libraries to the plugin dir after building with py2app. Once there,
the qt_plugpath term works its OSX magic.
Thanks!
Scott
