[PyQt] stand alone QFileDialog

[Janwillem van Dijk]

Thanks for paying attention to my question. It was about as far as I 
could get. The example below I made (unfortunaly more based on intuition 
than understanding) works when called from the command line. However, 
when called from inside the Eric5 IDE the dialog returns the results but 
hangs. This made me think my solution is incorrect.

Any comments very welcome, cheers!

def open_files(default_dir=None):
     """Returns list of filenames optionally given a default dir"""
     from sys import argv
     from os import environ
     from PyQt4.QtGui import QApplication, QFileDialog
     if default_dir == None:
         default_dir = environ['HOME']
     app = QApplication(argv)
     filenames = QFileDialog.getOpenFileNames(directory=default_dir)
     app.exit()
     return list(filenames)

if __name__ == '__main__':
     print('open dialog')
     lst = open_files()
     print('dialog finished')
     for fname in lst:
         print(fname)

for completeness the TkInter version that does work both from the 
commandline and from Eric5:
def open_files(default_dir=None):
     """Returns list of filenames+paths given default dir"""
     from os import environ
     from Tkinter import Tk
     import tkFileDialog
     if default_dir == None:
         default_dir = environ['HOME']
     root = Tk()
     root.withdraw()  # Hide root window
     filenames = tkFileDialog.askopenfilenames(initialdir=default_dir, 
multiple=True)
     return list(filenames)

if __name__ == '__main__':
     print('open dialog')
     lst = open_files()
     print('dialog finished')
     for fname in lst:
         print(fname)
