1. Qt 模块简介

Qt由许多模块组成,They support functions in different fields,主要分为 Essentials 和 Add-On.

Qt Essential 是基本模块,They are available on all supported development platforms and tested target platforms.Basic modules are generic,适用于大多数Qt应用程序.

Qt Add-On is an add-on module/扩展模块,Developed for special purpose.These modules may only be available on some development platforms.Many add-on modules are either fully functional,Exists for backward compatibility,Or only for certain platforms.Each add-in module specifies its compatibility separately.

1.1 Qt基本模块

Qt The basic modules are as follows：

模块描述
Qt Core所有基于Qt的应用程序的基础,其他模块使用的核心非图形类.
Provides an object communication mechanism for signals and slots、并发和多线程、容器/事件系统、插件和I/O设施.
Qt D-BusDClasses for interprocess communication over the bus protocol.
是一种进程间通信(IPC)和远程过程调用(RPC)机制,Generally used for many-to-many communication.
Qt GUI图形用户界面（GUI）组件的基类.
Included with windows⼝系统的集成、事件处理、OpenGL和OpenGL ES集成、2D图像、字体、拖放等.
这些类⼀般在Qt⽤户界⾯类内部使⽤,当然也可以⽤for accessing the bottom layerOpenGL ES 图像API.
Qt GuiThe module provides all the graphics⽤户界⾯All programs need to pass⽤功能.
Qt Network提供跨平台的⽹络功能,Makes network programming easier and more portable.
Qt QML用于QML和JavaScript语言.
Qt Quick⼀种基于 Qt 的⾼degree animated⽤户界⾯,适合于移动平台开发,用于构建具有自定义用户界面的高度动态应用程序的声明性框架.
Qt Quick Controls提供轻量级QML类型,用于为桌面、Create high-performance user interfaces for embedded and mobile devices.These types follow a simple style architecture,非常有效.
Qt Quick Dialogs用于从QtA type of express application that creates and interacts with system dialogs.
Qt Quick Layouts用于在 Qt Quick 2 中安排项目的布局.
Qt Quick TestQMLA unit testing framework for applications,The test cases start with JavaScriptwritten in the form of a function.
注：二进制兼容性保证不适用于 Qt 快速测试.但是,It will remain source code compatible.
Qt Test用于单元测试 Qt 应用程序和库的类.
注意：二进制兼容性保证不适用于 Qt 测试. 但是,它将保持源兼容.
Qt Widgets扩展Qt GUI模块的C++窗口类 .
