python - 如何在 kivy 中制作具有图像作为按钮和文本的自定义类？

Question

如何在kivy中制作具有图像/ png图标作为按钮和文本的自定义类，并使用该自定义类避免代码中的重复行？

我是 kivy 和 python 的新手。基本思想是创建一个类，它由一个圆形矢量图标作为投资组合和它下面的投资组合名称组成。所以我可以在需要的地方多次复制它。
请帮忙。提前致谢。

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.config import Config
from kivy.uix.label import Label
from kivy.uix.button import Button

class custombutton(Button, Label, BoxLayout):
    pass

class pfselectwindow(BoxLayout):
    Config.set('graphics', 'borderless', 'True')
    Config.set('graphics', 'width', '900')
    Config.set('graphics', 'height', '600')
    Config.write()
    def __init__(self, **kwargs):
        super().__init__(**kwargs)


class pfselectApp(App):
    def build(self, **kwargs):
        return pfselectwindow()

if __name__ == "__main__":
    app =pfselectApp()
    app.run()
