    Detailed Description

    In an MVC architecture, a MapGraphicsView represents the view and a map represents the model.

    A MapGraphicsView implements a map view as a QGraphicsView widget. It is used in user interfaces coded with C++.

    Example:

    Create a MapGraphicsView and set as central widget:

    // create the map view
    m_mapView = new MapGraphicsView(this);
    // set central widget with the map view on the QMainWindow
    setCentralWidget(m_mapView);

    See also Map, MapView, and GeoView.
