推荐答案

您必须创建2个QFileSystemModel，一个显示目录，另一个显示文件.要更改QListView的视图，必须使用单击的信号，并使用QModelIndex设置新的rootIndex.

You have to create 2 QFileSystemModel, one will show the directories and the other the files. To change the view of the QListView you must use the clicked signal, using the QModelIndex you set the new rootIndex.

import sys

from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

class Widget(QWidget):
    def __init__(self, *args, **kwargs):
        QWidget.__init__(self, *args, **kwargs)
        hlay = QHBoxLayout(self)
        self.treeview = QTreeView()
        self.listview = QListView()
        hlay.addWidget(self.treeview)
        hlay.addWidget(self.listview)

        path = QDir.rootPath()

        self.dirModel = QFileSystemModel()
        self.dirModel.setRootPath(QDir.rootPath())
        self.dirModel.setFilter(QDir.NoDotAndDotDot | QDir.AllDirs)

        self.fileModel = QFileSystemModel()
        self.fileModel.setFilter(QDir.NoDotAndDotDot |  QDir.Files)

        self.treeview.setModel(self.dirModel)
        self.listview.setModel(self.fileModel)

        self.treeview.setRootIndex(self.dirModel.index(path))
        self.listview.setRootIndex(self.fileModel.index(path))

        self.treeview.clicked.connect(self.on_clicked)

    def on_clicked(self, index):
        path = self.dirModel.fileInfo(index).absoluteFilePath()
        self.listview.setRootIndex(self.fileModel.setRootPath(path))


if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = Widget()
    w.show()
    sys.exit(app.exec_())
