[Urwid] urwid.Pile() - ValueError: too many values to unpack

[Bernardo Torres]

Just fixed. Apparently, ui.get_cols_rows() is only available under the
wrapper. New code:

class Interface:
  def __init__(self):
    server = xmlrpclib.ServerProxy("http://localhost:8082/")
    modules = server.list_modules()
    self.ui = urwid.curses_display.Screen()
    self.ui.register_palette([
      ('header', 'white', 'black', 'standout'),
      ('module', 'white', 'dark green'),
      ('text', 'black', 'dark blue'),
      ('title', 'white', 'dark blue', 'standout'),
      ('tip', 'dark red', 'dark cyan', 'standout'),
      ('bg', 'black', 'dark blue'),
    ])
    mods = []
    for mod in modules:
      mods.append(urwid.AttrWrap(urwid.Text(mod), 'module'))
    mods = urwid.ListBox(mods)
    title = urwid.AttrWrap(urwid.Text(('header', "Diag\n"),
align="center"), 'title')
    footer = urwid.Text(('tip', "ESC - Sair"))
    help = ""
    for module in modules:
      for method in server.module_methods(module):
        doc = docextract.DocString(server.system.methodHelp(module+'.'+method))
        help += module+'.'+method+': '+doc.description+"\n"
    play = urwid.ListBox([urwid.Text(('header', help))])
    self.body = urwid.Columns([('weight', 1, mods), ('weight', 4,
play)], dividechars=1, focus_column=0)
    self.box = urwid.AttrWrap(urwid.Frame(self.body, title, footer,
focus_part='body'), 'bg')
    self.ui.run_wrapper(self.main)

  def main(self):
    self.size = self.ui.get_cols_rows()
    self.canvas = self.box.render(self.size)
    while True:
      self.ui.draw_screen(self.size, self.canvas)
      time.sleep(1)
i = Interface()
