Qt Graphics View Framework 简介

Qt Graphics View Framework （以下简称GVF）是一套成熟的基于Qt Widgets的框架，为大量二维物件的交互提供了优化的管理方法和渲染机制。 这个框架内建了专用事件传递架构，使得物件可以处理键盘时间和鼠标时间，从而允许被选取，移动和旋转等。 此外这个框架提供了BSP(Binary Space partitioning)树索引模式，以快速地定位物件，从而也加速了区域的渲染，为实时显示提供了支持。

 

GVF首次亮相于Qt 4.2，替换了QCanvas。
架构

GVF由三部分组成，场景、视图和物件， 类似于Model View Framework中的模型、视图和代表元。
