Qt's Modules

Qt4模块详解
本文详细介绍了Qt4的各种模块,包括核心非GUI类的QtCore、GUI组件的QtGui、网络编程的QtNetwork等。此外还涵盖了OpenGL支持、数据库集成、XML处理等多个方面。

Qt 4 consists of several modules, each of which lives in a separate library.

 

QtCore Core non-GUI classes used by other modules

QtGui Graphical user interface components

QtNetwork Classes for network programming

QtOpenGL OpenGL support classes

QtSql Classes for database integration using SQL

QtSvg Classes for displaying the contents of SVG files

QtXml Classes for handling XML

QtDesigner Classes for extending Qt Designer

QtUiTools Classes for handling Qt Designer forms in applications

QtAssistant Support for online help

If you use qmake to build your projects, the QtCore and QtGui modules are included by default. To link only against QtCore, add the following line to your .pro file:
