Questions tagged [qtreeview]

QTreeView is a class in Qt framework. It provides a default model/view implementation of a tree view.

A QTreeView implements a tree representation of items from a model. This class is used to provide standard hierarchical lists that were previously provided by the QListView class, but using the more flexible approach provided by Qt's model/view architecture.

The official Qt documentation can be found here for Qt 4.8 and here for Qt 5.
