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3(イベントとプロパティ)、3.4(演習問題)、演習3.4の解答を求めてみる。

コード

Python 3

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

LabelBase.register(DEFAULT_FONT, 'NotoSansCJKjp-Regular.otf')


class MyFloatLayout(FloatLayout):
    def __init__(self, *args, **kwargs):
        FloatLayout.__init__(self, *args, *kwargs)
        self.no = 1

    def on_touch_down(self, touch):
        print(f'{touch} ({self.no})')
        self.add_widget(Button(text=f'タッチ! ({self.no})',
                               size_hint=[0.2, 0.2],
                               center=touch.pos))
        self.no += 1


class SampleApp(App):
    def build(self):
        float_layout = MyFloatLayout()
        return float_layout


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

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