Re: [pygtk] os.popen to gtk.TextView
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()

This sort of thing seems reasonable, but I found in CANVAS that the more
I did while gtk.events_pending() loops, the more problems I ran into.
Threading is tough - you're going to want to do a callback based
solution for this.

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()

def __init__(self, w, fn, font):
self.__fn = fn
self.__w = w
self.__b = w.get_buffer()
self.__ins = self.__b.get_mark('insert')
self.__font = font
you can simply rename them.
def __init__(self, w, fn, font):
self.passed_fn = fn
self.use_this_window = w
self.the_textbuffer = w.get_buffer()
self.insert_mark = self.__b.get_mark('insert')
self.__font = font
If you want full terminal capability you can use the vte terminal
widget. It is the library widget that gnome-terminal uses. It has a
python interface, not as complete as the 'c' interface, but does work.
It will give you a full speed fully working terminal in a pygtk app.

Try looking at os.popen3
You can do something like
[example]
That isn't what I want. On your example I must wait until the command in
os.popen3 has finished.
If the command need some minutes the user doesn't know what the script
doing. And I want that the user can see the output in "real-time".
You know what I mean?

Isn't this the topic of FAQ 14.23?
http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq14.023.htp
Yes, thats true. But if I use this I must wait until 'commend' has
finished, too.
And I want to insert the output without time lag.

Try looking at os.popen3
You can do something like
stdin, stdout, stderr = os.popen3(command)
while not done:
try:
outputstr = stdout.readline()
if outputstr == '':
done = 1
else:
# do something with textview and outputstr
except (IOError):
# ignore interrupted system calls here otherwise
done = 1
stdin.close()
stdout.close()
stderr.close()

[pygtk] os.popen to gtk.TextView
Hi.
I want to write the output of os.popen('command') to a gtk.TextView.
But I don't know how. :(
If I use

textview.insert_at_cursor(line)
I must wait untils 'command' has finished.
Is there a better way? Is it not possible to wrote the output directly
to a gtk.TextView?
I have found some documentation about pipes or related things. But
because my english isn't very good I doesn't understand it realy.
