DatePicker

Material Design spec, Date picker

Date pickers let people select a date, or a range of dates.

• Date pickers can display past, present, or future dates

• Three types: docked, modal, modal input

• Clearly indicate important dates, such as current and selected days

• Follow common patterns, like a calendar view

1. Docked date picker

2. Modal date picker

3. Modal date input

KivyMD provides the following date pickers classes for use:

• MDDockedDatePicker

• MDModalDatePicker

• MDModalInputDatePicker

MDDockedDatePicker

Docked datepickers allow the selection of a specific date and year. The docked datepicker displays a date input field by default, and a dropdown calendar appears when the user taps on the input field. Either form of date entry can be interacted with.

Docked date pickers are ideal for navigating dates in both the near future or past and the distant future or past, as they provide multiple ways to select dates.

MDModalDatePicker

Modal date pickers navigate across dates in several ways:

• To navigate across months, swipe horizontally (not implemented in KivyMD)

• To navigate across years, scroll vertically (not implemented in KivyMD)

• To access the year picker, tap the year

Don’t use a modal date picker to prompt for dates in the distant past or future, such as a date of birth. In these cases, use a modal input picker or a docked datepicker instead.

MDModalInputDatePicker

Modal date inputs allow the manual entry of dates using the numbers on a keyboard. Users can input a date or a range of dates in a dialog.

        on_release: app.show_date_picker()

        MDButtonText:
            text: "Open modal date picker dialog"
'''


class Example(MDApp):
    def build(self):
        self.theme_cls.primary_palette = "Olive"
        return Builder.load_string(KV)

    def show_date_picker(self):
        date_dialog = MDModalInputDatePicker()
        date_dialog.open()


Example().run()

The range of available dates

To display only the selected date range, use the min_date and max_date parameters:

def show_modal_date_picker(self, *args):
    MDModalDatePicker(
        mark_today=False,
        min_date=datetime.date.today(),
        max_date=datetime.date(
            datetime.date.today().year,
            datetime.date.today().month,
            datetime.date.today().day + 4,
        ),
    ).open()

Only dates in the specified range will be available for selection:

Select the date range

To select the date range, use the mode parameter with the value “range”:

def show_modal_date_picker(self, *args):
    MDModalDatePicker(mode="range").open()

Setting the date range manually

def show_modal_date_picker(self, *args):
    MDModalInputDatePicker(mode="range").open()
