Spinner¶
New in version 1.4.0.
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_value:
print: "The spinner {} has text {}".format(self, self.value)
