How do you mean this?
Befor os.popen or after os.popen?
Normaly I use this:
while gtk.events_pending():
gtk.main_iteration()
for line in os.popen('do something').readlines():
tbuffer.insert_at_cursor(line)
Here I must wait until 'do something' has finished.
If I use the next example the command from os.popen will be executed two
times.
for line in os.popen('do something').readlines():
while gtk.events_pending():
gtk.main_iteration()
tbuffer.insert_at_cursor(line)

Try using readline() instead of readlines() on the pipe. I would create
the pipe in a separate line of code.
I have make some experiments. And I have found a answer to my problem. :)
child = pexpect.spawn('find /usr -type d')
while gtk.events_pending():
gtk.main_iteration()
line = child.readline()
while line:
while gtk.events_pending():
gtk.main_iteration()
tbuffer1.insert_at_cursor(line)
tview1.scroll_to_mark(tbmark1, 0.05, True, 0.0, 1.0)
line = child.readline()
regards
Marcus
