QTableWidget先去读全部的,再进行分页显示,表格固定的是一百行,每次操作对这一百行数据进行刷新,虚拟出完整表格的效果。 测试:QTableWidge分页显示1千万行数据,此种方法优化了文件的读取,可以快速的读取全部的文件内容,表格也只100行,占用内存较小。但是读取了全部大文件,文件占用的较大部分的内存。

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;
基于Qt做的一个虚拟仪表盘的实例,可以作为参考
软件作用:检测串口功能 软件说明: 波特率:115200 字节数:8 校验位:0 停止位:1 软件使用说明:需要发送的文件必须放在“E:\\test\\test.txt”,接收到的文件将会在 “E:\\test\\test1.txt”;打开串口后,就开始了自动接收数据,接收完成后,按下“停 止接收数据”;如果要发送数据,请点击“发送键”,发送完成,会弹出“发送完成”。 软件测试情况:发送功能用“超级终端多次测试”,10M内,没发生错误。接收功能1M以 下,基本不会发生错误,1M以上性能不稳定。
