Create visually appealing and feature-rich applications by using Qt 5 and the C++ language Qt 5, the latest version of Qt, enables you to develop applications with complex user interfaces for multiple targets. It provides you with faster and smarter ways to create modern UIs and applications for multiple platforms. This book will teach you to design and build graphical user interfaces that are functional, appealing, and user-friendly. In the initial part of the book, you will learn what Qt 5 is and what you can do with it. You will explore the Qt Designer, discover the different types of widgets generally used in Qt 5, and then connect your application to the database to perform dynamic operations. Next, you will be introduced to Qt 5 chart which allows you to easily render different types of graphs and charts and incorporate List View Widgets in your application. You will also work with various Qt modules, like QtLocation, QtWebEngine, and the networking module through the course of the book. Finally, we will focus on cross-platform development with QT 5 that enables you to code once and run it everywhere, including mobile platforms. By the end of this book, you will have successfully learned about high-end GUI applications and will be capable of building many more powerful, cross-platform applications. What You Will Learn Implement tools provided by Qt 5 to design a beautiful GUI Understand different types of graphs and charts supported by Qt 5 Create a web browser using the Qt 5 WebEngine module and web view widget Connect to the MySQL database and display data obtained from it onto the Qt 5 GUI Incorporate the Qt 5 multimedia and networking module in your application Develop Google Map-like applications using Qt 5’s location module Discover cross-platform development by exporting the Qt 5 application to different platforms Uncover the secrets behind debugging Qt 5 and C++ applications

QWT全称是Qt Widgets for Technical Applications，是一个基于LGPL版权协议的开源项目， 可生成各种统计图。它为具有技术专业背景的程序提供GUI组件和一组实用类，其目标是以基于2D方式的窗体部件来显示数据， 数据源以数值，数组或一组浮点数等方式提供， 输出方式可以是Curves（曲线），Slider（滚动条），Dials（圆盘），Compasses（仪表盘）等等。该工具库基于Qt开发，所以也继承了Qt的跨平台特性。 【QWT基类】[2]QwtAbstractScale： 包含刻度尺的所有类的抽象基类； QwtAbstractScaleDraw：绘制刻度尺的抽象基类； QwtAbstractSlider：滑块部件的抽象基类； QwtAlphaColorMap：可以改变颜色的alpha值； QwtAnalogClock：时钟的模拟类； QwtArrayData：包含2个QwtArray<double>实例的数据类； QwtArrowButton：箭头按钮； QwtClipper：剪贴板类； QwtColorMap：提供数值到颜色的映射功能； QwtCompass：指南针部件； QwtCompassMagnetNeedle：指南针部件的磁针； QwtCompassRose：罗盘部件的抽象基类； QwtCompassWindArrow：风向标的指示器；

前言 本科期间学习过C语言，拿到了计算机二级证书，此外主要自学MATLAB和Python进行深度学习相关的编程。一直以为C++和C#与C语言大同小异，没有重视，在学校的项目需要用C++进行编程，并且甲方点名界面要用Qt做，觉得MFC太难看。也罢，近乎于从0开始，趁着新肺，在家自学C++与Qt，借此记录，欢迎大家交流。 一、开发环境 1、Windows 10 64位； 2、Qt 5.8.0（MINGW编译器，利用Qt Creator而不是宇宙最强IDE——vs）； 3、OpenCV 3.2.0 二、环境配置 参考的是：拜小白教你Qt5.8.0+OpenCV3.2.0配置教程(详细版) 虽然作者讲
