55 \brief The QColumnView class provides a model/view implementation of a column view.-
56 \ingroup model-view-
57 \ingroup advanced-
58 \inmodule QtWidgets-
59-
60 QColumnView displays a model in a number of QListViews, one for each-
61 hierarchy in the tree. This is sometimes referred to as a cascading list.-

63 The QColumnView class is one of the \l{Model/View Classes}-
64 and is part of Qt's \l{Model/View Programming}{model/view framework}.-
65-
66 QColumnView implements the interfaces defined by the-
67 QAbstractItemView class to allow it to display data provided by-
68 models derived from the QAbstractItemModel class.-
