Convert QStingList to Python list

[Peter Chant]

The following code generates a QStringList:

fileNames = QFileDialog.getOpenFileNames(None,"Chose raw file",".",)

Printing it:

print "Files selected "+QStringList(fileNames)

Results in:

TypeError: cannot concatenate 'str' and 'QStringList' objects

Any idea how to convert a QStingList into a python list? pythonQtConv seems
to come up in google but I've no idea how to import or invoke it.

Thoughts?

You say that fileNames already is a QStringList. Why are you trying to
convert it to a QStringList then?
Anyway, it wouldn't work with a python list either.

Try it out yourself in the interactive interpreter. Here's a sample session:

files = QStringList(["alpha.txt", "beta.txt"])
print files

print list(files) [PyQt4.QtCore.QString(u'alpha.txt'), PyQt4.QtCore.QString(u'beta.txt')]
print [str(f) for f in files] ['alpha.txt', 'beta.txt']
print "Selected files:", ", ".join(str(f) for f in files) Selected files: alpha.txt, beta.txt
files = QStringList([u"äöü.txt", "beta.txt"])
print "Selected files:", ", ".join(str(f) for f in files)

Selected files:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 1, in <genexpr>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2:
ordinal not in range(128)Selected files: äöü.txt, beta.txt

Peter,

thanks. I've got some way to go with python and have only just started
looking at Qt, your help has been very useful.
