python - Pyqt5 List QtPushbutton 添加border-image

Question

我正在使用 Python 3 ( Pycharm ) 和 Pyqt5 (Windows 10)

我需要使用 QPushbutton 列表。我设法改变了按钮的颜色，没关系。尽管如此，我无法将border-image（相同的QT）的图像更改为添加按钮的函数（Add_Buttons_KA_IU）我的目录结构：

我的项目：

|-> Vision_Room.py

|-> Ressource -> LightOff.png

首先，如果你要给每个按钮添加QSS，则不需要使用objectName，另一方面，问题是因为你不明白“：”是什么意思，“：”表示你正在使用一个 qresource (.qrc)，它是一个允许在 Qt 中通用存储文件的文件，它是一个虚拟路径，你不应该使用那些“：”，因为你没有使用它。另一方面，最好有文件的完整路径以避免出现问题，但它也必须易于管理，因此解决方案是获取 .py 的路径并将其与资源的相对路径连接起来关于.py，所以你可以移动你的项目，即使那样它也能工作。
