Detailed Description

To display non Fary drawings.

This class is used for plane drawings of graphs which are not Fary drawings. Fary drawings uses the editor to be displayed.
For each drawing algorithm, one has to write a function taking as arguments a pointer on a QPainter and a pointer on this class. pigalePaint uses a pointer to such a function to display the drawing..
It works using a copy of the graph.
