Hi there
I've got a queue (multiprocessing.queue) that is fed by subprocesses and is
consisting of entries like ("server01", "unpacking /tmp/my.tar.gz"). I want
to read from the queue and put the server/message couple into urwid via
Columns, like this:
from urwid.curses_display import Screen
columns = urwid.Columns(listboxes)
screen = Screen()
screen.start()
while is_alive(processes):
if not display_queue.empty():
server, message = display_queue.get()
add_to_listbox(server, listboxes)
screen.draw_screen((cols,rows), columns)
else:
time.sleep(0.05)
screen.stop()
I've got 2 questions:
1. what do I need to put into (cols, rows) in the draw_screen call?
2. am I completely on the wrong track? What would be a better solution to
"be in control myself" because I
a) want to quit the drawing whenever all the subprocesses finished
b) need to periodically check if there are new messages in the queue?
