摘　　要：Qt是一个跨平台的C++GUI应用构架,它提供了丰富的窗口部件集,具有面向对象、易于扩展、真正的组件编程等特点。目前Linux上最为流行的KDE桌面环境就是建立在Qt库的基础之上。伴随着KDE的快速发展和普及,Qt逐渐成为Linux窗口平台上进行软件开发时的GUI首选,而信号与槽作为Qt的核心机制在Qt编程中有着广泛的应用,本文研究了信号与槽的通信机制、元对象工具以及在实际使用过程中应注意的一些问题。Qt is a C＋＋ GUI application architecture of cross platform, it provides a rich set of widgets, object oriented, easy extension, the real component programming etc.The most popular KDE desktop environment of Linux＇s is established on the basis of the Qt library. With the rapid development of the KDE and the popularity of Linux, Qt has gradually become the window platform during the software development of GUI choice, and the signal and slot as the core mechanism of Qt is widely used in Qt programming, communication mechanism, this paper studies the signal and slot of the meta object facility and some problems that should be paid attention to in the process of practical use.
