CGAL 5.6.1 - CGAL and the Qt Graphics View Framework

#include <CGAL/Qt/GraphicsItem.h>

Inherits from


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


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.


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