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4(KV言語)、4.5(演習問題)、演習4.2の解答を求めてみる。

コード

Python 3

#!/usr/bin/env python3
from kivy.app import App
# 日本語用
from kivy.core.text import LabelBase, DEFAULT_FONT
LabelBase.register(DEFAULT_FONT, 'NotoSansCJKjp-Regular.otf')


class Sample2App(App):
    pass


Sample2App().run()

KV言語

BoxLayout:
    orientation: 'vertical'
    Image:
        size_hint_y: 0.8
        id: image
    BoxLayout:
        size_hint_y: 0.2
        Button:
            text: '建物'
            on_press: image.source = 'building.jpg'; print(self)
        Button:
            text: '銀座'
            on_press: image.source = 'ginza.jpg'; print(self)
        Button:
            text: 'kamimura'
            on_press: image.source = 'kamimura.png'; print(self)
