## Inherits from

QGraphicsItem.

Inherited by CGAL::Qt::CircularArcGraphicsItem< CK >, CGAL::Qt::TriangulationGraphicsItem< T >, and CGAL::Qt::VoronoiGraphicsItem< DT >.

## Definition

The CGAL graphics items hold pointers to CGAL data structures.

When a data structure changes, a signal is emitted. An object derived from type `GraphicsItem` must provide an implementation of the virtual slot `modelChanged()`. This typically triggers redrawing, as well as recomputation of the bounding box which in turn may trigger redrawing of overlapping graphics items.

## Slots

virtual void | modelChanged ()
| This slot must be provided by derived classes.
