Development And Application Of Microwindows Widget Lib Based On Embedded Platform

With the improvement of computer hardware design level, more and more software development work is on the GUI. And more and more embedded systems need GUI spport. GUI design for different embedded platform is one of the kyes to the design of linux embedded system, which has become more and more important.This paper mainly uses a widely used GUI, which is Microwindows as an example to discuss the research and application of relevant technology. And illustrate in detail how to use specific technology to the development of medical monitor software.At last the function of monitor software is realized by developing a relevant Microwindows widget. Main related work is as follows:1. If Microwindows API is directly used to develop monitor software, a lot of duplication and similar work will be done due to the complexity of the GUI of monitor. So this text designs and realizes a Microwindows widget lib by using OOP thought and re-organizing Microwindows API, for reusing the developed module to the largest extent.2. Finally the widget lib is used in the development of monitor software based on EW-AM3902 platform, and function of relevant module is realized.
