python库“urwid”是否包含用于读取日期的小部件（datepicker）？

Question

npyscreen具有用于选择日期的小部件"DateCombo" and "TitleDateCombo"。在

乌尔韦德有什么相似之处吗？ 如果没有，是否有推荐的第三方库？在

下面是一个使用npyscreen的示例：

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

import npyscreen

class DateForm(npyscreen.Form):
    def afterEditing(self):
        self.parentApp.setNextForm(None)

    def create(self):
        self.date = self.add(npyscreen.TitleDateCombo, name="Date")

class TestApplication(npyscreen.NPSAppManaged):
    def onStart(self):
        new_user = self.addForm("MAIN", DateForm, name="Read Date")

if __name__ == "__main__":
    TestApplication().run()

Answer 1

python库^{}似乎没有包含日期选择器（stateof2018）。所以我写了一篇（初步的）文章。在

这个类叫做^{}，并且可以通过pip安装。在

import urwid                                                       # installed via pip

# Color schemes that specify the appearance off focus and on focus.
PALETTE = [("reveal_focus", "black", "white")]

dp = DatePicker(highlight_prop=("reveal_focus", None))        # By default, the focused picker is not highlighted!

pile = urwid.Pile([urwid.Text("press additionally the key modifier (default is 'ctrl')."),
                   urwid.Divider(" "),
                   dp])

loop = urwid.MainLoop(urwid.Filler(pile, "top"),
                      PALETTE)
loop.run()

不，urwid没有日期选择器，它是一个复杂的小部件，需要自己的项目来实现，因为这些小部件通常需要考虑日期格式、区域设置等

我不知道任何实现它的urwid库，并且通过快速扫描我知道的库也找不到。在

您可以尝试购买一个库，但您可能会有更好的运气实现一个自己的具体需要。在
