Is there a datepicker which can be used in combination with the python library urwid?

[AFoeee]

Hello,
the module 'npyscreen' has two widgets to pick dates ('DateCombo' and 'TitleDateCombo').

I was told that the python library 'urwid' does not have a date picker, which is due to the complexity.
Unfortunately I could not find such a third-party library.

Although there are projects like 'khal', these are mostly designed as stand-alone applications and not as 'urwid' widgets.

Does anyone know such a project?
If there is no such thing, with which approaches can this lack be compensated?

'urwid.Edit' (basically a text field) has the problem that invalid data can be entered. Although a conversion to 'datetime.date' and exception handling does the trick, this is very clunky.

Here is the 'npyscreen' date picker and the associated source code:

#! /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()

This question has also been posted on stackoverflow.

Best regards
