Thank you Ryan, Olivier, James for your feedback. When I came in this morning,
the port install of py25-pyqt4 was complete.
I have a problem with my app build using py2app ... perhaps you can help. Its
related to Qt/PyQt and possibly an issue with QImage and missing jpg encoder.
My python script uses PyQt to display 8 jpg image sequences in a multi-panel
viewport. These images are generated from 8 cameras. I have a feeling the app
cannot find jpg encoder. However everything works perfectly when I run same
script directly from python.
This works:
----------------------------
> which python
/opt/local/bin/python
>python mvrv.py
----------------------
But app created from py2app does not display images:
I created setup.py file according to instructions on the web and ran "python
setup.py py2app".
---------------------------------------------------------
from setuptools import setup
APP = ['mvrv.py']
OPTIONS = {'argv_emulation': True, 'includes':
['sip','PyQt4._qt','PyQt4.QtCore','PyQt4.QtGui'],
'excludes':['PyQt4.QtDesigner','PyQt4.QtNetwork','PyQt4.QtOpenGl','PyQt4.QtScript','PyQt4.QtSql','PyQt4.QtTest','PyQt4.QtWebKit','PyQt4.QtXml','PyQt4.phonon']}
setup(
app=APP,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
------------------------------------
... so when I double-click mvrv.app under dist folder, the GUI launches fine.
The interface shows image frame numbers as caching progresses, but the numbers
change fast and no images are displayed. I saw this behavior when I first began
development on Windows. In that case, I was getting output from terminal shell
... something like "QImage() called with null image". Someone said this was due
to missing jpg encoder and our windows build engineer rebuilt my python
environment ... and everything worked.
Back in mac land, I ran my script, mvrv.py, via python interpreter. In this
case, caching proceeded as expected and image playback worked. Since I don't
get broken behavior from python interpreter I can only guess that somehow in
the app build something is missing with respect to jpg encoding ... because the
GUI behaviour totally works in all other respects.
Any help, hints would be greatly appreciated.
Thanks,
Suzanne
