Iterating all items inside QListView using python

Question

I have a QlistView inside is which a checkboxes (created dynamically) with item name (QstandardItem). And below Qlistview is a checkbox named DatacheckercheckBox1. What I want is when this DatacheckercheckBox1 checkbox statechanges to "Checked", all the checkboxes inside the QlistView should be checked. I have made a signal for DatacheckercheckBox1 checkbox by

self.dlg.DatacheckercheckBox1.stateChanged.connect(self.selectAll)

i dont have idea in writing a method that should iterate all the items inside Qlistview and make the checkboxes next to it "Checked" if its not checked already.

Answer 1

Use the model to iterate over the items:

model = self.listView.model()
for index in range(model.rowCount()):
    item = model.item(index)
    if item.isCheckable() and item.checkState() == QtCore.Qt.Unchecked:
        item.setCheckState(QtCore.Qt.Checked)
