QTreeView *treeView = new QTreeView(this); QStandardItemModel *model = new QStandardItemModel(this); treeView->setModel(model); QItemSelectionModel *selectionModel = treeView->selectionModel();
QListView *listView = new QListView(this); QStringList items = {"Item 1", "Item 2", "Item 3"}; QStringListModel *model = new QStringListModel(items, this); listView->setModel(model); QItemSelectionModel *selectionModel = listView->selectionModel(); connect(selectionModel, &QItemSelectionModel::selectionChanged, this, &MyClass::selectionChanged);In this example, we create a QListView and a QStringListModel to populate it. We then get the selection model for the list view, and connect its `selectionChanged()` signal to a slot called `selectionChanged()` in a class called MyClass. Overall, QItemSelectionModel is a useful tool for managing selections in various Qt views. It can help you keep track of which items are selected, perform operations on those items, and respond to changes in the selection. It is included in the Qt Widgets module.
