\macro Q_CLASSINFO(Name, Value) | |
The QAbstractProxyModel class provides a base class for proxy item models that can do sorting, filtering or other data processing tasks.
\inmodule QtCore.
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.
To subclass QAbstractProxyModel, you need to implement mapFromSource() and mapToSource(). The mapSelectionFromSource() and mapSelectionToSource() functions only need to be reimplemented if you need a behavior different from the default behavior.

Equivalent to calling createIndex on the source model.
This method is useful if your proxy model wants to maintain the parent-child relationship of items in the source model. When reimplementing mapToSource(), you can call this method to create an index for row row and column col of the source model.
A typical use would be to save the internal pointer coming from the source model in the proxy index when reimplementing mapFromSource() and use the same internal pointer as internalPtr to recover the original source index when reimplementing mapToSource().

Sets the given sourceModel to be processed by the proxy model.
Subclasses should call beginResetModel() at the beginning of the method, disconnect from the old model, call this method, connect to the new model, and call endResetModel().
