Python PyQt QFileSystemModel根路径

Question

这是我必须显示名为"C:\ Myfolder"的目录的树视图的代码.

import sys
from PyQt4 import QtGui,QtCore

class Myview(QtGui.QMainWindow):
    def __init__(self,parent=None):
        QtGui.QMainWindow.__init__(self)
        model = QtGui.QFileSystemModel()
        model.setRootPath('C:\Myfolder')
        view = QtGui.QTreeView()
        view.setModel(model)
        self.setCentralWidget(view)


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    myview = Myview()
    myview.show()
    sys.exit(app.exec_())

即使我将其设置RootPath为"C:\ Myfolder",树视图也会显示所有驱动器和文件夹.

我怎么能限制QFileSystemModel,使TreeView里面的"C:\ MyFolder文件"只显示项目目录？

Answer 1

您需要view.setRootIndex(model.index("C:\Myfolder"))根据QFileSystemModel文档添加.
