Refresh test in urwid.Text

[Stensborg]

I am trying output some test to the screen, but I have to update the text when some external data changes.

So I made this test program, and even though it works, I think I am doing something very wrong, since it seems like I am creating loops within loops.

Can someone tell me what i am doing wrong?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

#!/usr/bin/python import urwid   def unhandled_input(key):     if key == 'q':         raise urwid.ExitMainLoop()   def refresh(_loop,_data):     outputTxt       = ['COMP3      ', (red_bg, 'DOWN   '), "Bla\n"]     outputTxt      += ['COMP4      ', (green_bg, 'UP     '), "Bla bla\n"]       txt             = urwid.Text(outputTxt)     fill            = urwid.Filler(txt, 'top')     loop            = urwid.MainLoop(fill, unhandled_input=unhandled_input)     loop.set_alarm_in(1,refresh)     loop.run()   red_bg = urwid.AttrSpec('default', 'dark red') green_bg = urwid.AttrSpec('default', 'dark green')   outputTxt       = ['COMP1      ', (red_bg, 'DOWN   '), "Bla\n"] outputTxt      += ['COMP2      ', (green_bg, 'UP     '), "Bla bla\n"]   txt             = urwid.Text(outputTxt) fill            = urwid.Filler(txt, 'top') loop            = urwid.MainLoop(fill, unhandled_input=unhandled_input) loop.set_alarm_in(1,refresh) loop.run()

Found the solution, had to change the refresh method to this.

1 2 3 4 5 6

def refresh(_loop,_data):     outputTxt       = ['COMP3      ', (red_bg, 'DOWN   '), "Bla\n"]     outputTxt      += ['COMP4      ', (green_bg, 'UP     '), "Bla bla\n"]       txt.set_text(outputTxt)     loop.set_alarm_in(1,refresh)
