QPropertyAnimation动画 可以运行的例子

#include <QtGui/QApplication>

#include "mainwindow.h"

#include <QPixmap>

#include <QPropertyAnimation>

#include <QLabel>

int main(int argc, char *argv[])

{

    /*

    QApplication a(argc, argv);

    MainWindow w;

    w.show();

    return a.exec();

    */

    QApplication app(argc,argv);

    QWidget *w=new QWidget();

    w->resize(300,400);

    QPixmap birdimg(20,20);

    birdimg.fill(Qt::red);

    QLabel *bird_1=new QLabel(w);

    bird_1->setPixmap(birdimg);

    QPropertyAnimation *anim1=new QPropertyAnimation(bird_1, "pos");

    anim1->setDuration(2000);

    anim1->setStartValue(QPoint(0, 0));

    anim1->setEndValue(QPoint(200, 300));

    anim1->start();

    bird_1->move(-40,-40);

    w->show();

    return app.exec();

}
