Detailed Description

A QtCanvas is derived from the Qt widget QGLWidget; the associated VRS canvas using OpenGL as rendering engine can be accessed by the canvas() method.

Constructor arguments include width and height in pixels, the parent widget if any, the properties of the OpenGL framebuffer defined in GLCanvas, an optional name, and an optional technique processor. NOTE: Since QtCanvas is NOT derived from any VRS classes the SO<> mechanism cannot be used for holding pointers to objects of it!!!
