開発環境

Kivyプログラミング ―Pythonで作るマルチタッチアプリ― (実践Pythonライブラリー) (原口 和也(著)、久保 幹雄(監修)、朝倉書店)の2(ウィジェット)、2.5(演習問題)、演習2.2を取り組んでみる。

コード(Emacs)

Python 3

#!/usr/bin/env python3
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.boxlayout import BoxLayout
from kivy.core.text import LabelBase, DEFAULT_FONT

LabelBase.register(DEFAULT_FONT, 'ipaexg.ttf')


class MyButton(Button):
    def __init__(self, n, *args, **kwargs):
        Button.__init__(self, *args, **kwargs)
        self.n = n

    def on_press(self):
        self.size_hint_x *= 1.1
        print(f'ボタン{self.n}: {self.size_hint_x}')


class SampleApp(App):
    def build(self):
        boxlayout = BoxLayout(orientation='horizontal')
        button1 = MyButton(1, text='1ボタン')
        button2 = MyButton(2, text='2ボタン')
        boxlayout.add_widget(button1)
        boxlayout.add_widget(button2)
        return boxlayout


if __name__ == '__main__':
    SampleApp().run()

入出力結果(Terminal, cmd(コマンドプロンプト), Jupyter(IPython))
