針對(duì)嵌入式系統(tǒng)低處理能力和低存儲(chǔ)空間的特點(diǎn)，設(shè)計(jì)了GUI 平臺(tái)的分層體系結(jié)構(gòu)，
并在此分層體系結(jié)構(gòu)的基礎(chǔ)上用C 和C++語言實(shí)現(xiàn)。GUI 平臺(tái)中不但提供了繪圖、窗口、
編輯器、瀏覽器等窗口功能，而且設(shè)計(jì)了適合工控領(lǐng)域的波形顯示器功能。波形顯示器直接建立在內(nèi)核驅(qū)動(dòng)程序之上，具有數(shù)據(jù)波形顯示、波形處理、圖形旋轉(zhuǎn)等強(qiáng)大的波形處理能力。此分層體系結(jié)構(gòu)有利于用戶對(duì)其功能地添加和修改。

Abstract: On account of the low operation speed and low storage capacity of the Linux system, a layer structure for GUI system is designed. The system is realized by using C and C++ language. The GUI system supports the fundamental windows function, such as charting, windows, editor and browser, and so on. Moreover, the waveform monitor function built on Linux operation system’s deriver directly is also designed, which contains of displaying waveform, handling waveform , rotating graph and these multi-functional capability. This layer structure make the user convenient to add their own function and modify the function already existed.
