[Urwid] nested frames -> footer contents change problem

[Rybarczyk Tomasz]

Hi,

It's me again...  Previous simple example is working well in newer
urwid version but there is a little bit more complicated one which
fails for me (with 0.9.8.2 ;-)). I want to change content of inner
Frame footer while browsing listbox but instead this uwrid overwrites
outer Frame footer. Additionally from some point (if you scroll list
down) it's changing inner footer as it should. Is it again my fault?


import urwid.raw_display
import urwid
import sys


class TextField(urwid.WidgetWrap):
    def __init__(self, text):
        self.widget = urwid.Text(text)
        self.w = urwid.AttrWrap(self.widget,'body','focus')
        urwid.WidgetWrap.__init__(self, self.w)
        self.selected = False

    def keypress(self, size, key):
        return key

    def selectable(self):
        return True



def run():
    some_text_list = urwid.SimpleListWalker(map(TextField, (("this is
some content of list"*10).split())))
    listbox = urwid.ListBox(some_text_list)

    inner_foot = urwid.Text("inner_foot")
    inner_head = urwid.Text("inner_head")

    inner_frame = urwid.Frame(body=listbox, footer=inner_foot,
header=inner_head)

    outer_foot = urwid.Text("outer_foot")
    outer_head = urwid.Text("outer_head")
    outer_frame = urwid.Frame(body=inner_frame, footer=outer_foot,
header=outer_head)

    size = ui.get_cols_rows()
    canvas = outer_frame.render(size, focus=1)
    ui.draw_screen(size, canvas)

    while True:
        size = ui.get_cols_rows()
        key = ui.get_input()
        for k in key:
            if k == 'j' or k=='down':
                outer_frame.keypress(size, 'down')
                inner_foot.set_text(listbox.get_focus()[0].widget.text)
            elif k == 'k' or k=='up':
                outer_frame.keypress(size, 'up')
                inner_foot.set_text(listbox.get_focus()[0].widget.text)

        canvas = outer_frame.render(size, focus=1)
        ui.draw_screen(size, canvas)


palette = [
    ('body', 'black', 'light gray'),
    ('focus', 'dark gray', 'dark blue', 'standout')]

ui = urwid.raw_display.Screen()
ui.register_palette(palette)
ui.run_wrapper(run)


Thanks in advance
