[PySide] Help with resource files

[Sean Fisk]

OK, I have an interim solution. While I do believe that QFile.readAll() should return the file contents as a QByteArray, QResource.data() seems to work! Here is the code: 
#!/usr/bin/env python # test.py import PySide from PySide import QtCore import resources # Versions print 'Running PySide {0} / Qt {1}'.format( PySide.__version__, QtCore.__version__) print 'PySide compiled with Qt {0}'.format(QtCore.qVersion()) # Read resource test_txt = QtCore.QResource(':/test.txt') data = test_txt.data() print "type(data()): {0}".format(type(data)) print "data(): `{0}'".format(data)
which yields
Running PySide 1.1.2 / Qt 4.8.4 PySide compiled with Qt 4.8.4 type(data()): <type 'buffer'> data(): `This is just a test. '


This returns the resource as a Python buffer (http://docs.python.org/2/library/functions.html#buffer) type. I'm hoping I can coerce this into the source for a font or image in Qt.

More updates if I get it to work.

Sincerely,
