Two QListView box one showing files in a folder and one shows selected files from the first QListview

I want to display the files in my listview from my folder with path described in the code and able to
select them, the files I selected will be displayed in my listview2, However, the listview doesn't show
the files in this path. Can anyone help me with it?

  • Do you want that when a file is selected then it is added to the other QListView or only what is selected is shown?

  • Are you asking me ?, I have not yet pointed out a solution so I do not understand your question. I still have doubts about what you want, for example let's say that 5 files of 100 have been selected and they are in the second QListView, and let's say that one of those 5 files is deselected. Should that same item be eliminated in the second QListView? if not, how would an item in the second QListView be deleted?

The files are not displayed because you have not set a rootPath in the QFileSystemModel.



On the other hand the second QListView must have a model where items are added or removed as they are selected or deselected, for this you must use the selectionChanged signal of selectionModel() of the first QListView, that signal transports the information of the selected and deselected items.



To change the color you must obtain the QStandardItem and use the setData() method with the Qt::BackgroundRole role. In the example in each second the color is changed randomly



import sys
import random
from PyQt5 import QtCore, QtGui, QtWidgets


class Widget(QtWidgets.QWidget):
def __init__(self, *args, **kwargs):
super(Widget, self).__init__(*args, **kwargs)
self.listview = QtWidgets.QListView()
self.listview2 = QtWidgets.QListView()

path = r'C:UsersDesktopProject'

self.fileModel = QtWidgets.QFileSystemModel(self)
self.fileModel.setRootPath(path)
self.fileModel.setFilter(QtCore.QDir.NoDotAndDotDot | QtCore.QDir.Files)
self.listview.setModel(self.fileModel)
self.listview.setRootIndex(self.fileModel.index(path))
self.listview.selectionModel().selectionChanged.connect(self.on_selectionChanged)
self.listview.setSelectionMode(QtWidgets.QAbstractItemView.ExtendedSelection)

self.model = QtGui.QStandardItemModel(self)
self.listview2.setModel(self.model)

hlay = QtWidgets.QHBoxLayout(self)
hlay.addWidget(self.listview)
hlay.addWidget(self.listview2)

timer = QtCore.QTimer(self, interval=1000, timeout=self.test_color)
timer.start()

def on_selectionChanged(self, selected, deselected):
roles = (QtCore.Qt.DisplayRole,
QtWidgets.QFileSystemModel.FilePathRole,
QtWidgets.QFileSystemModel.FileNameRole,
QtCore.Qt.DecorationRole)

for ix in selected.indexes():
it = QtGui.QStandardItem(ix.data())
for role in roles:
it.setData(ix.data(role), role)
it.setData(QtGui.QColor("green"), QtCore.Qt.BackgroundRole)
self.model.appendRow(it)

filter_role = QtWidgets.QFileSystemModel.FilePathRole
for ix in deselected.indexes():
for index in self.model.match(ix.parent(), filter_role, ix.data(filter_role), -1, QtCore.Qt.MatchExactly):
self.model.removeRow(index.row())

def test_color(self):
if self.model.rowCount() > 0:
n_e = random.randint(0, self.model.rowCount())
rows_red = random.sample(range(self.model.rowCount()), n_e)
for row in range(self.model.rowCount()):
it = self.model.item(row)
if row in rows_red:
it.setData(QtGui.QColor("red"), QtCore.Qt.BackgroundRole)
else:
it.setData(QtGui.QColor("green"), QtCore.Qt.BackgroundRole)

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

The files are not displayed because you have not set a rootPath in the QFileSystemModel.



On the other hand the second QListView must have a model where items are added or removed as they are selected or deselected, for this you must use the selectionChanged signal of selectionModel() of the first QListView, that signal transports the information of the selected and deselected items.



To change the color you must obtain the QStandardItem and use the setData() method with the Qt::BackgroundRole role. In the example in each second the color is changed randomly



import sys
import random
from PyQt5 import QtCore, QtGui, QtWidgets


class Widget(QtWidgets.QWidget):
def __init__(self, *args, **kwargs):
super(Widget, self).__init__(*args, **kwargs)
self.listview = QtWidgets.QListView()
self.listview2 = QtWidgets.QListView()

path = r'C:UsersDesktopProject'

self.fileModel = QtWidgets.QFileSystemModel(self)
self.fileModel.setRootPath(path)
self.fileModel.setFilter(QtCore.QDir.NoDotAndDotDot | QtCore.QDir.Files)
self.listview.setModel(self.fileModel)
self.listview.setRootIndex(self.fileModel.index(path))
self.listview.selectionModel().selectionChanged.connect(self.on_selectionChanged)
self.listview.setSelectionMode(QtWidgets.QAbstractItemView.ExtendedSelection)

self.model = QtGui.QStandardItemModel(self)
self.listview2.setModel(self.model)

hlay = QtWidgets.QHBoxLayout(self)
hlay.addWidget(self.listview)
hlay.addWidget(self.listview2)

timer = QtCore.QTimer(self, interval=1000, timeout=self.test_color)
timer.start()

def on_selectionChanged(self, selected, deselected):
roles = (QtCore.Qt.DisplayRole,
QtWidgets.QFileSystemModel.FilePathRole,
QtWidgets.QFileSystemModel.FileNameRole,
QtCore.Qt.DecorationRole)

for ix in selected.indexes():
it = QtGui.QStandardItem(ix.data())
for role in roles:
it.setData(ix.data(role), role)
it.setData(QtGui.QColor("green"), QtCore.Qt.BackgroundRole)
self.model.appendRow(it)

filter_role = QtWidgets.QFileSystemModel.FilePathRole
for ix in deselected.indexes():
for index in self.model.match(ix.parent(), filter_role, ix.data(filter_role), -1, QtCore.Qt.MatchExactly):
self.model.removeRow(index.row())

def test_color(self):
if self.model.rowCount() > 0:
n_e = random.randint(0, self.model.rowCount())
rows_red = random.sample(range(self.model.rowCount()), n_e)
for row in range(self.model.rowCount()):
it = self.model.item(row)
if row in rows_red:
it.setData(QtGui.QColor("red"), QtCore.Qt.BackgroundRole)
else:
it.setData(QtGui.QColor("green"), QtCore.Qt.BackgroundRole)

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

  • Thank you so much! just one quick question, the ix in selected.indexes() are PyQt5.QtCore.QModelIndex object, how do I retreive the file name of the ix

  • @Cindy use ix.data() or ix.data(QtWidgets.QFileSystemModel.FilePathRole) or ix.data(QtWidgets.QFileSystemModel.FileNameRole)
