1、首先需要在头文件上加上#include <QMessageBox>

2、开始拖几个按钮在界面上，就是pushButton，最后就是通过转到槽的方式进行添加程序

void MainWindow::on_pushButton_2_clicked()
{//QString info = QString("打开不成功,\n请查看连接情况!").arg("111");QString info = QString("打开不成功,\n请查看连接情况!");QMessageBox::warning(NULL, "warning", info, QMessageBox::Yes | QMessageBox::No, QMessageBox::Yes);
}void MainWindow::on_pushButton_3_clicked()
{QMessageBox::information(this, "error", "bug!");
}void MainWindow::on_pushButton_4_clicked()
{QMessageBox::StandardButton reply;reply = QMessageBox::question(this, "question", "Do you want to travel?", QMessageBox::Yes | QMessageBox::No);if(reply == QMessageBox::Yes){QMessageBox::information(this, "ok", "你想好地方了吗?");}else{QMessageBox::information(this, "no", "你需要再想想哦");}
}void MainWindow::on_pushButton_5_clicked()
{QMessageBox::question(this, "NOTICE", "Are you beautiful?",QMessageBox::YesToAll|QMessageBox::Yes|QMessageBox::No);
}
