Detailed Description

The paint system enables painting on screen and print devices using the same API, and is primarily based on the QPainter, QPaintDevice, and QPaintEngine classes.

QPainter is used to perform drawing operations, QPaintDevice is an abstraction of a two-dimensional space that can be painted on using a QPainter, and QPaintEngine provides the interface that the painter uses to draw onto different types of devices. The %&PaintEngine class is used internally by QPainter and %&PaintDevice, and is hidden from application programmers unless they create their own device type.

The main benefit of this approach is that all painting follows the same painting pipeline making it easy to add support for new features and providing default implementations for unsupported ones.

As an alternative use the CsOpenGL library which offers classes to use OpenGL in your application. The CsOpenGL library provides an OpenGL widget class which can be used just like any other CopperSpice widget, except it opens an OpenGL display buffer where the OpenGL API can be used to render the contents.
