Python GUI (glade) to display output of shell process


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?


Here is a link that also displays another way of doing this.

I found this to be very insightful, maybe someone else can use these tips.

glade is only a program to build gui with gtk so when you ask for a <em>glade object</em> maybe you should ask for <em>gtk widget</em> and in this case textbuffer and textview chould be a solution or maybe treeview and liststore. subprocess.Popen has stdout and stderr arguments that can accept a file-like object. you can create an adapter that writes to the textbuffer or add items in the liststore


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_widget('txtview') proc = subprocess.Popen('ls -al /home'.split(), stdout=subprocess.PIPE, stderr = subprocess.STDOUT) while True: line = proc.stdout.readline() viewer.get_buffer().instert_at_cursor(line) if not line: break
