摘　　要：Qt作为一个跨平台的C++图形用户界面(GUI)应用程序开发工具,在Linux系统中得到了广泛的应用。在使用Qt开发GUI应用程序时,经常需要设计和实现对话框窗口。在阐述了Qt特性、Linux Qt4环境搭建方法及Qt4标准对话框与自定义对话框的区别的基础上,介绍了用Qt4布局管理器实现用户界面的相关技术,分析了用Qt4设计自定义对话框的基本流程,完成了自定义对话框的设计与实现。Qt, as a cross-platform C＋＋ graphical user interface （GUI） application development tool, has been widely used in Limtx system. It is often necessary to design and implement the dialog window when developing GUI applications using Qt. The article expounds the characteristics of Qt and the method of setting up Linux Qt4 developing environment, and describes the difference between the Qt4 standard dialog and the custom dialog. On this basis, the article introduces the related technologies of using Qt4 layout manager to implement the user interface, analyzes the basic process of using Qt4 to design custom login dialog, and completes the design and implementation of custom dialog box.
