My first Qt program

 

//我的第一个Qt程序 留个纪念吧！ #include <QtGui/QApplication>
#include "qmlapplicationviewer.h"
#include <QLabel>
#include <QPushButton>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel("<h2><i>Hello </i>"
                              "<font color = blue> Qt! </font></h2>");
    label->show();

    QPushButton *button = new QPushButton("Quit");
    QObject::connect(button, SIGNAL(clicked()), &app, SLOT(quit()));
    button->show();

    return app.exec();
}
