#include <CGAL/Qt/Basic_viewer.h>

Definition

The class QApplication_and_basic_viewer regroups a Basic_viewer and Qt QApplication.

The QApplication is created in the constructor, but started by the run() method. This allows for example users to modify the on_key_pressed method of the Basic_viewer to define their own behavior.

This class requires CGAL_Qt6, 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_Qt6 and add the definition CGAL_USE_BASIC_VIEWER.

Examples: Basic_viewer/draw_surface_mesh_small_faces.cpp.
