◆ draw()
template<class P >
void CGAL::draw 
( 
const P & 
ap  ) 

#include <CGAL/draw_polygon_2.h>
opens a new window and draws ap
, an instance of the CGAL::Polygon_2
class.
A call to this function is blocking, that is the program continues as soon as the user closes the window. This function requires CGAL_Qt5
, and is only available if the macro CGAL_USE_BASIC_VIEWER
is defined. Linking with the cmake target CGAL::CGAL_Basic_viewer
will link with CGAL_Qt5
and add the definition CGAL_USE_BASIC_VIEWER
.
