CheckBox
|
||||
========

|
||||
|
||||
:class:`CheckBox` is a specific two-state button that can be either checked or
|
||||
unchecked. If the CheckBox is in a Group, it becomes a Radio button.
|
||||
As with the :class:`~kivy.uix.togglebutton.ToggleButton`, only one Radio button
|
||||
at a time can be selected when the :attr:`CheckBox.group` is set.
|
||||
|
||||
An example usage::
|
||||
|
||||
from kivy.uix.checkbox import CheckBox
|
||||
|
||||
# ...
|
||||
|
||||
def on_checkbox_active(checkbox, value):
|
||||
if value:
|
||||
print('The checkbox', checkbox, 'is active')
|
||||
else:
|
||||
print('The checkbox', checkbox, 'is inactive')
|
||||
|
||||
checkbox = CheckBox()
|
||||
checkbox.bind(active=on_checkbox_active)
