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()

No, urwid doesn't have a datepicker, it's a complex widget to implement which deserves its own project, since these widgets usually need to take into consideration date format, locale, etc.

I don't know any urwid library that implements it and couldn't find any by scanning quickly the ones I know.

You can try to shop for a library, but you might have better luck implementing one yourself with your specific needs.

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

# 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])
