\class QProxyModel
|

\obsolete
|
||||
\brief The QProxyModel class provides support for processing data
|
||||
passed between another model and a view.
|
||||
|
||||
\ingroup model-view
|
||||
\inmodule QtWidgets
|
||||
|
||||
If you want to do filtering and sorting, see QSortFilterProxyModel.
|
||||
|
||||
Proxy models provide a standard model interface that can be used to
|
||||
manipulate the data retrieved through an underlying model. They can be used to
|
||||
perform operations such as sorting and filtering on the data obtained without
|
||||
changing the contents of the model.
|
||||
|
||||
Just as with subclasses of QAbstractItemView, QProxyModel provides the setModel()
|
||||
function that is used to specify the model to be acted on by the proxy.
|
||||
Views can be connected to either the underlying model or the proxy model with
|
||||
\l QAbstractItemView::setModel().
|
||||
|
||||
Since views rely on the information provided in model indexes to identify
|
||||
items of data from models, and to position these items in some visual
|
||||
representation, proxy models must create their own model indexes instead of
|
||||
supplying model indexes from their underlying models.
