pygtk and long running process

[Robert]

Hi,

I have a command line app that can take up to 20 minutes to complete and
every minute or so updates it's status (spits it out to console). I am
writing a front end for this app in python/gtk and was wondering what
command I use to a) invoke the command and b) how to capture it's out put
and for instance update a text box.

Regards,

Rob

os.popen() will probably do what you want.

e.g.:

import os

some_external_command = "ls"
prog_output = os.popen(some_external_command)
for status_line in prog_output:
print status_line

As for the latter part of (b)....

I don't know much about pygtk, but I imagine you should be able to put
the code that monitors the external program in a thread, and then
whenever you get some new status information update the text box.
