[FIXED] Is it possible to have a QListWidget select multiple setCurrentItems

Issue

In PyQt I can have QListWidget select an item programmatically using QListWidget.setCurrentItem(item). And this, of course, will select an item for me inside my QListWidget.

However, I'm wondering if there exists a method like setCurrentItems([item1, item2, item3]) where if I give a list, it will select all the items in QListWidget that match those items.

Right now my current implementation only allows me to select one item. In this case, the item 'data2'

index = ['data', 'data1', 'data2']
for i in index:
    matching_items = listWidget.findItems(i, QtCore.Qt.MatchExactly)
    for item in matching_items:
        listWidget.setCurrentItem(item)

It would be cool if something like this could be done.

index = ['data', 'data1', 'data2']
for i in index:
    matching_items.append(listWidget.findItems(i, QtCore.Qt.MatchExactly))
listWidget.setCurrentItems(matching_items)

Solution

QListWidget by default supports a single selection, you must change the selection mode with setSelectionMode, in your case:

listWidget.setSelectionMode(QListWidget.MultiSelection)

If you want a QListWidgetItem to be selected you must use setSelected(True).

Example:

if __name__ == '__main__':
    app = QApplication(sys.argv)
    listWidget = QListWidget()

    listWidget.addItems(["data{}".format(i) for i in range(10)])

    listWidget.setSelectionMode(QListWidget.MultiSelection)
    index = ['data2', 'data3', 'data5']
    for i in index:
        matching_items = listWidget.findItems(i, Qt.MatchExactly)
        for item in matching_items:
            item.setSelected(True)

    listWidget.show()
    sys.exit(app.exec_())
