我使用urwid库遇到set_alarm问题。基本上，当你运行它并在Chapman上按Enter键时，你会得到以下错误。我不太了解urwid，它似乎缺乏文档，我试图寻找比较的例子，但我找不到任何。
import urwid
import pyfiglet
class data():
drpepper = pyfiglet.Figlet(font='doom')
choices = u'Chapman Cleese Gilliam Idle Jones Palin'.split()
def menu(self, title, choices):
body = [urwid.Text(title), urwid.Divider()]
for c in choices:
button = urwid.Button(c)
if c == "Chapman":
urwid.connect_signal(button, 'click', self.info, c)
body.append(urwid.AttrMap(button, None, focus_map='reversed'))
return urwid.ListBox(urwid.SimpleFocusListWalker(body))
def item_chosen(self, button, choice):
response = urwid.Text([u'You chose ', choice, u'\n'])
done = urwid.Button(u'Ok')
urwid.connect_signal(done, 'click', info)
main.original_widget = urwid.Filler(urwid.Pile([response, urwid.AttrMap(done, None, focus_map='reversed')]))
def info(self, button, choice):
response = urwid.Text(self.drpepper.renderText("text"), align="center")
response2 = urwid.Text("Test")
with open("/home/jt/works?.txt", "a+") as data:
data.write("THIS IS A TEST 2")
done = urwid.Button(u'Ok')
self.main.original_widget = urwid.Filler(urwid.Pile([self.loop.set_alarm_in(5, response), response2]))
def exit_program(self, button):
raise urwid.ExitMainLoop()
def mainish(self):
main = urwid.Padding(self.menu(u'Pythons', self.choices), left=2, right=2)
top = urwid.Overlay(main, urwid.SolidFill(u'\N{MEDIUM SHADE}'),
align='center', width=('relative', 60),
valign='middle', height=('relative', 60),
min_width=20, min_height=9)
self.loop = urwid.MainLoop(top, palette=[('reversed', 'standout', '')])
self.loop.run()
start = data（） start.mainish（）
这是错误

答案 0 :(得分：0)
最后，经过无数个小时，你们几分钟就会发布一些东西。我喜欢python的支持社区（讽刺）...我喜欢人们声称它有一个很棒的支持社区，当我无法得到答案时。
好的，结束咆哮。这是为那些正在挣扎的人，因为没有其他人会帮助你。
Collection在这里你看到main.original_widget清除屏幕并保留在一个位置。我无法解释为什么清楚，因为没有人会帮助。但是，我意识到你必须创建一个储备。
它需要文本编辑或其他东西。您无法调用窗口小部件中的函数。为什么？没有线索。询问Urwid社区是否可以获得单一回复。继续前进
通过创建保留，您可以创建一个var say＆＃34; self.x = urwid.Text（＆＃34;＆＃34;）＆＃34;没有任何内部我认为保留它。然后，通过创建say self.test.set_alarm_in（4）
来创建警报然后它将在4秒左右的时间内调用函数test（）。所以你可以很容易地把self.x.set_text（＆＃34; hello world＆＃34;）放进去，它应该可以工作。
