Example (doesn't work)

Code:

proc = subprocess.Popen('/home/user/test.sh',
                               shell=True,
                               stdout=subprocess.PIPE,
                               )
for line in iter(proc.stdout.readline,''):
    self.displaybox.append(line)
    print line

One way to do this is to call the application's processEvents() method every so often. You could try calling it after you read each line, though it might be a bit inefficient to do so. The global QApplication instance is available as the qApp object, or you can obtain it using QApplication.instance().
