By researching the structure of graphic abstract layer based on the open source project Mozilla,then a series of interfaces of graphic abstract layer on a embed library MiniGUI is realized,the portability of embed browser is greatly improved.

• 从解决此问题入手,以开源代码Mozilla为基础,通过研究视窗抽象层的结构,在嵌入图形库MiniGUI上设计并实现视窗抽象层的一系列接口,可以大大提高嵌入式浏览器的可移植性。
