Does the python library "urwid" contain a widget for reading in dates (datepicker)?

npyscreen has the widgets "DateCombo" and "TitleDateCombo" for picking dates.

Is there anything similar in urwid? If not, are there any recommended third-party libraries?

Here is an example which uses npyscreen:

#! /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()

It seems that the python library urwid does not include a date picker (state of 2018). Therefore I wrote a (rudimentary) one.

The class is called additional_urwid_widgets.DatePicker and can be installed via pip.

For a stand alone example, which illustrates the functionality of the widget, see here.

For more (and simpler) examples, see here.

For a more detailed explanation of the parameters and options, see the corresponding github wiki entry.

Some Examples

Minimal

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

from additional_urwid_widgets import DatePicker, MODIFIER_KEY      # installed via pip
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()

Not Today

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

import datetime
from additional_urwid_widgets import DatePicker, MODIFIER_KEY      # installed via pip
import urwid                                                       # installed via pip

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

not_today = datetime.date(2018, 2, 20)

dp = DatePicker(initial_date=not_today,
                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()
