No problem. It's a learning process for me, too! > I need to know when the process awaits input on it's stdin.

Yes, I hoped I would find a signal that tells you when more input is required, but it looks like it's not quite as simple as that. [Code snippet snipped] The wroteToStdin() signal from QProcess is helpful when you're writing to the other process's stdin stream, but it won't tell you when the other process is waiting for input. If you were using streams directly in Python, you might be able to tell whether the stdin stream is waiting, but it doesn't look like it's possible with QProcess. :-( Still, you need to know what the other process is asking for, so there may be a way to tell by monitoring the output of the process. I imagine that "apt-get upgrade" asks specific questions by writing to stdout and reading back from stdin, so you might be able to look for these messages in its output. Of course, what you look for depends on the language in use - I notice that your application is running a Norwegian language version of apt-get http://developer.berlios.de/dbimage.php?id=2608 so things could get interesting if you're looking for specific English strings in the output. :-) If you want, experiment a bit with this approach, and let us know how you get on. Otherwise, the alternative approach might be to use Python's process-handling support.
