## Detailed Description
该QPaintEngine类提供了如何的抽象定义[QPainter](qpainter.html)绘制到一个给定的设备在给定平台上。
的Qt 4.0提供QPaintEngine的几个预制的实现,因为我们支持不同的画家后端。我们为每个窗口系统和绘画框架,我们支持提供一个绘制引擎。这包括X11在Unix / Linux和[CoreGraphics](qpaintengine.html#Type-enum)在Mac OS X此外,我们提供QPaintEngine的实现[OpenGL](qpaintengine.html#Type-enum)(可通过[QGLWidget](qglwidget.html))和[PostScript](qpaintengine.html#Type-enum)(通过QPSPrinter在X11访问) 。此外,还有一个基于光栅的涂料引擎,是一个后备,当引擎不支持某些功能。
如果一个人想用[QPainter](qpainter.html)绘制到不同的后端,必须继承QPaintEngine并重新实现其所有的虚函数。该QPaintEngine执行,然后提供通过继承[QPaintDevice](qpaintdevice.html)并重新实现虚函数[QPaintDevice.paintEngine](qpaintdevice.html#paintEngine)( ) 。
QPaintEngine创建和拥有的[QPaintDevice](qpaintdevice.html)创建它。
该QPaintEngine办法反对的Qt 3的的一大优点[QPainter](qpainter.html)/ QPaintDevice.cmd ( )方法,它现在可以适应多种技术在每个平台上,充分利用每一个发挥到淋漓尽致。
