Python GUI (glade) to display output of shell process

Question

I'm writing a python application that runs several subprocesses using subprocess.Popen objects. I have a glade GUI and want to display the output of these commands (running in subprocess.Popen) in the gui in real time.

Can anyone suggest a way to do this? What glade object do I need to use and how to redirect the output?

Answer 1

After lots of reading and not getting the results I wanted, I found another method that works.

It goes like this

#!/usr/bine/env python
import subprocess
import gtk

### Of course, you should have the gui built and know which widgets to use for this.
viewer = self.builder.get_object('txtview')
proc = subprocess.Popen('ls -al /home'.split(), stdout=subprocess.PIPE, stderr = subprocess.STDOUT)
while True:
    line = proc.stdout.readline()
    viewer.get_buffer().insert_at_cursor(line)
    if not line:
       break
