Python的Urwid问题set_alarm
问题描述：
我遇到了使用库urwid的set_alarm问题。基本上，当你运行它并击中查普曼时，你会得到下面的错误。我对urwid知之甚少，似乎缺乏文档，我试图寻找可以比较的例子，但是我找不到任何东西。Python的Urwid问题set_alarm
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()
开始=数据（） start.mainish（）
这是错误

答
后一千年的组合，我终于得到了它。知识？我随机地将黑客代码保存在一起，直到它最终像bruteforce猜测一样工作。
最后，无尽的时间，这将让你们几分钟后发布的东西。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。
好吧，结束咆哮。这是为了那些因为别人不会帮助你而挣扎的人。
self.main.original_widget = urwid.Filler(urwid.Pile([self.loop.set_alarm_in(5, response), response2]))
在这里您会看到main.original_widget清除屏幕并保留在某个位置。我无法解释清楚，因为没有人会帮忙。但是，我意识到你必须创建一个储备。
它期望一个文本编辑或其他东西。你不能在窗口部件中调用一个函数。为什么？没有线索。询问Urwid社区，如果你甚至可以得到一个单一的回应。继续前进
通过创建预留，您可以创建一个var说“self.x = urwid.Text（”“）”，其中没有任何内容，我认为它保留了它。之后，你通过创建一个告警来创建一个告警self.test.set_alarm_in（4）
然后它会调用函数test（）4秒左右。所以你可以很容易地把self.x.set_text（“你好世界”），它应该工作。
