漏网之鱼，QFileSystemModel中已经设置setFilter( QDir.Files)，还是极少数目录被显示


其它目录正常
如果改成QListView()，没有日期等信息显示，纠结中，请高人指教！

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 = QTreeView()
    hlay.addWidget(self.treeview)
    hlay.addWidget(self.listview)
    #self.listview = QListView()#没有日期等信息
    
    #path = QDir.rootPath()
    path = ''

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

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

    self.treeview.setModel(self.dirModel)
    self.listview.setModel(self.fileModel)
    self.listview.setSelectionMode(QAbstractItemView.ExtendedSelection)
    self.treeview.setColumnHidden(1, True)
    self.treeview.setColumnHidden(2, True)
    self.treeview.setColumnWidth(0, 500)
    self.listview.setColumnWidth(0, 500)

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

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

def on_clicked(self, index):
    path = self.dirModel.fileInfo(index).absoluteFilePath()
    self.listview.setRootIndex(self.fileModel.setRootPath(path))
def itemClicked(self, Qmodelidx):
    text = self.fileModel.data(Qmodelidx)
    print(text)
    indexItem = self.fileModel.index(Qmodelidx.row(), 0, Qmodelidx.parent())
    #print(indexItem)
    fileName = self.fileModel.data(indexItem)
    print(fileName)
    print(self.dirModel.filePath(Qmodelidx))

app = QApplication(sys.argv)
w = Widget()
w.show()
sys.exit(app.exec_())
