C++ Qt c++；VS代码：如何使用相对文件路径？

我在Mac上的VS代码中使用Qt6框架。 我有一个Window.h和Window.cpp文件来使用QOpenGLWindow和QOPENGLFUNCTION创建窗口

窗户

[已解决]

我在res文件夹中创建了一个res.qrc文件，代码如下：

res.qrc

现在我可以使用着色器文件的相对路径：

Window.cpp

谢谢@chehrlic

只需以源目录作为工作目录运行应用程序。如果通过VSCode运行应用程序，则相应地配置VSCode。或者将着色器放入Qt资源文件或相对于可执行文件，并使用QCoreApplication:：applicationDirPath（）
