A ListView of checkboxes in PyQt

I want to display a QListView where each item is a checkbox with some label. The checkboxes should be visible at all times. One way I can think of is using a custom delegate and QAbstractListModel. Are there simpler ways? Can you provide the simplest snippet that does this?

Thanks in advance

Solution

  • If you are writing your own model, just include the Qt.ItemIsUserCheckable flag in the return value from the flags() method, and ensure that you return a valid value for the Qt.CheckStateRole from the data() method.

    If you use the QStandardItemModel class, include the Qt.ItemIsUserCheckable flag in those you pass to each item's setFlags() method, and set the check state for the Qt.CheckStateRole with its setData() method.

    In an interactive Python session, type the following:

    from PyQt4.QtGui import *

model = QStandardItemModel()
item = QStandardItem("Item")
item.setFlags(Qt.ItemIsUserCheckable | Qt.ItemIsEnabled)
item.setData(QVariant(Qt.Checked), Qt.CheckStateRole)
model.appendRow(item)

view = QListView()
view.setModel(model)
view.show()
