Re: [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 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,

That's good to know, Eric. Eventually we will be doing Windows distribution so I'm glad there are no problems.

Here is another update. I tried putting Lena on a button using QIcon on my OS X installation and it worked:

That leads me to believe it's a problem with QFile, not the actual generated resource file. I'm going to try messing around with the QResource class next.

Thanks for all the help, guys!

Thanks for the confirmation with Python 2 and 3 on Ubuntu. Although we

don't yet know whether it is a bug or just incorrect code by me.

Works fine for me on Windows (cygwin/bash shell but win32 version of

Python 2.7.2) if I open the file first.

I'm surprised there is no exception thrown if you don't do this.

I can try on OS X tonight.

...

# Read resource

test_txt = QtCore.QFile(':/test.txt')

test_txt.open(QtCore.QIODevice.ReadOnly | QtCore.QIODevice.Text)

print 'Does it exist?: {0}'.format(test_txt.exists())

print "readAll(): `{0}'".format(test_txt.readAll())

gives output

$ python test.py

Running PySide 1.1.0 / Qt 4.7.4

PySide compiled with Qt 4.7.4

Does it exist?: True

readAll(): `This is just a test.
