a button widget. You should see a button labelled 'plop' that will move with
an animation when clicked.

import kivy
kivy.require('1.0.7')

from kivy.animation import Animation
from kivy.app import App
from kivy.uix.button import Button


class TestApp(App):

    def animate(self, instance):
        # create an animation object. This object could be stored
        # and reused each call or reused across different widgets.
        # += is a sequential step, while &= is in parallel
        animation = Animation(pos=(100, 100), t='out_bounce')
        animation += Animation(pos=(200, 100), t='out_bounce')
        animation &= Animation(size=(500, 500))
        animation += Animation(size=(100, 50))

        # apply the animation on the button, passed in the "instance" argument
        # Notice that default 'click' animation (changing the button
        # color while the mouse is down) is unchanged.
        animation.start(instance)

    def build(self):
        # create a button, and  attach animate() method as a on_press handler
        button = Button(size_hint=(None, None), text='plop',
                        on_press=self.animate)
        return button


if __name__ == '__main__':
