Detailed Description

The QColumnView class provides a model/view implementation of a column view.

QColumnView displays a model in a number of QListViews, one for each hierarchy in the tree. This is sometimes referred to as a cascading list.

The QColumnView class is one of the Model/View Classes and is part of Qt's model/view framework.

QColumnView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class.
