How can I catch QTreeView deselected event?

Question

How can I catch QTreeView deselected event?Is there in QT this type event? Thanks

Answer 1

QAbstractItemView::selectionModel() will return a pointer to the selection model of the view. That model fires a signal whenever the selection is changed, whether it's selected or deselected.

Connect the QItemSelectionModel::selectionChanged(const QItemSelection & selected, const QItemSelection & deselected) signal to a slot in your code, and deal with the deselected parameter.
