Rootpath of FilesystemTreeview seems not work

[QiangZiBro]

Hi, bro, nice work! I find that QFileSystemModel.setRootPath seems not to work in PyQt5, so I modified some codes according to this and it works now
origin code

        self.fileSystemModel = QFileSystemModel()
        self.fileSystemModel.setRootPath('.')
        self.setModel(self.fileSystemModel)

modified

        # 设置根目录
        self.fileSystemModel = QFileSystemModel()  # 1
        self.setModel(self.fileSystemModel)  # 2
        self.fileSystemModel.setRootPath(QDir.rootPath())  # 3
        self.setRootIndex(self.fileSystemModel.index("/Users/mac/Pictures"))  # 4
