QItemSelectionModel Class Reference

List of all members.


Detailed Description

The QItemSelectionModel class keeps track of a view's selected items.

The QItemSelectionModel class is one of the {Model/View Classes} and is part of Qt's {Model/View Programming}{model/view framework}.

The selected items are stored using ranges. Whenever you want to modify the selected items use select() and provide either a QItemSelection, or a QModelIndex and a QItemSelectionModel::SelectionFlag.

The QItemSelectionModel takes a two layer approach to selection management, dealing with both selected items that have been committed and items that are part of the current selection. The current selected items are part of the current interactive selection (for example with rubber-band selection or keyboard-shift selections).

To update the currently selected items, use the bitwise OR of QItemSelectionModel::Current and any of the other SelectionFlags. If you omit the QItemSelectionModel::Current command, a new current selection will be created, and the previous one added to the whole selection. All functions operate on both layers; for example, selectedItems() will return items from both layers.
