[править] Подробное описание

The QAbstractProxyModel class provides a base class for proxy item models that can do sorting, filtering or other data processing tasks.

This class defines the standard interface that proxy models must use to be able to interoperate correctly with other model/view components. It is not supposed to be instantiated directly.

All standard proxy models are derived from the QAbstractProxyModel class. If you need to create a new proxy model class, it is usually better to subclass an existing class that provides the closest behavior to the one you want to provide. Proxy models that filter or sort items of data from a source model should be created by using or subclassing QSortFilterProxyModel.

QItemSelection QAbstractProxyModel::mapSelectionFromSource ( const QItemSelection & sourceSelection ) const [virtual]

Returns a proxy selection mapped from the specified sourceSelection.

Reimplement this method to map source selections to proxy selections.

[править]
QItemSelection QAbstractProxyModel::mapSelectionToSource ( const QItemSelection & proxySelection ) const [virtual]

Returns a source selection mapped from the specified proxySelection.

Reimplement this method to map proxy selections to source selections.

[править]
QModelIndex QAbstractProxyModel::mapToSource ( const QModelIndex & proxyIndex ) const [pure virtual]

Reimplement this function to return the model index in the source model that corresponds to the proxyIndex in the proxy model.

See also mapFromSource().

[править]
void QAbstractProxyModel::setSourceModel ( QAbstractItemModel * sourceModel ) [virtual]

Sets the given sourceModel to be processed by the proxy model.

See also sourceModel().

[править]
QAbstractItemModel * QAbstractProxyModel::sourceModel () const

Returns the model that contains the data that is available through the proxy model.
