本文主要是介绍Qt仿制Windows10记事本，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
使用Qt做的一个仿制windows10的简易记事本,只有部分功能和win10记事本有一点像.
先看效果图吧:
先使用Qt创建一个GUI widget Application 的 QMainWindow 项目,工程目录如下所示:
main.cpp
#include "mainwindow.h"
#include <QApplication>
#include <QTranslator>
#include <QCoreApplication>int main(int argc, char *argv[])
{QApplication a(argc, argv);QTranslator* pTranslator = new QTranslator();pTranslator->load(":/res/qm/qt_zh_CN.qm"); //资源里需要有这个文件QCoreApplication::installTranslator(pTranslator); //将字体对话框翻译成中文MainWindow w;w.show();return a.exec();
}
