Spinner is a widget that provides a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all the other available values from which the user can select a new one.

Example:

from kivy.base import runTouchApp
from kivy.uix.spinner import Spinner

spinner = Spinner(
    # default value shown
    text='Home',
    # available values
    values=('Home', 'Work', 'Other', 'Custom'),
    # just for positioning in our example
    size_hint=(None, None),
    size=(100, 44),
    pos_hint={'center_x': .5, 'center_y': .5})

def show_selected_value(spinner, text):
    print('The spinner', spinner, 'has text', text)

spinner.bind(text=show_selected_value)

runTouchApp(spinner)

Kv Example:

FloatLayout:
    Spinner:
        size_hint: None, None
        size: 100, 44
        pos_hint: {'center': (.5, .5)}
        text: 'Home'
        values: 'Home', 'Work', 'Other', 'Custom'
        on_text:
            print("The spinner {} has text {}".format(self, self.text))

Spinner class, see module documentation for more information.

dropdown_cls

Class used to display the dropdown list when the Spinner is pressed.

dropdown_cls is an ObjectProperty and defaults to DropDown.

Changed in version 1.8.0: If set to a string, the Factory will be used to resolve the class name.

is_open

By default, the spinner is not open. Set to True to open it.

is_open is a BooleanProperty and defaults to False.

New in version 1.4.0.

option_cls

Class used to display the options within the dropdown list displayed under the Spinner. The text property of the class will be used to represent the value.

The option class requires:

  • a text property, used to display the value.

  • an on_release event, used to trigger the option when pressed/touched.

  • a size_hint_y of None.

  • the height to be set.

option_cls is an ObjectProperty and defaults to SpinnerOption.

Changed in version 1.8.0: If you set a string, the Factory will be used to resolve the class.

sync_height

Each element in a dropdown list uses a default/user-supplied height. Set to True to propagate the Spinner’s height value to each dropdown list element.

New in version 1.10.0.

sync_height is a BooleanProperty and defaults to False.

text_autoupdate

Indicates if the spinner’s text should be automatically updated with the first value of the values property. Setting it to True will cause the spinner to update its text property every time attr:values are changed.

New in version 1.10.0.

text_autoupdate is a BooleanProperty and defaults to False.

values

Values that can be selected by the user. It must be a list of strings.
