61 \brief The QColumnView class provides a model/view implementation of a column view.-
62 \ingroup model-view-
63 \ingroup advanced-
64 \inmodule QtWidgets-
65-
66 QColumnView displays a model in a number of QListViews, one for each-
67 hierarchy in the tree. This is sometimes referred to as a cascading list.-
68-
69 The QColumnView class is one of the \l{Model/View Classes}-
70 and is part of Qt's \l{Model/View Programming}{model/view framework}.-
71-
72 QColumnView implements the interfaces defined by the-
73 QAbstractItemView class to allow it to display data provided by-
74 models derived from the QAbstractItemModel class.-
