应用程序框架在嵌入式系统中的应用

Application Framework Used in Embedded System

针对GUI开发工具FLTK(Fast Light Tool Kit在开发嵌入式系统应用程序中的不足之处,借鉴微软的MFC,建立了以FLTK为基础的嵌入式系统应用程序框架,实现窗口管理和非标准I/O操作事件的处理。引入消息映射机制和传递机制,实现在类成员函数中分布处理应用程序消息。该框架能提高应用程序开发效率,使程序更灵活和易于扩展。

FLTK（Fast Light Tool Kit）, one of GUI application development tools,has some disadvantage on developing applications for embedded system. Learning from MFC, an application framework based on FLTK is created for embedded system. Application windows can be managed effectively. Events from non-standard I/O devices can be processed directly. The framework contains message map and message routing, which process application messages in member functions distributed in classes. It improves application development. Applications developed for embedded system therefore turn out to be flexible and easily to extend.
