【转】Qt动画组的简单使用

#include "widget.h"

#include <QLabel>

#include <QPropertyAnimation>

#include <QtDebug>

#include <QtGui>

#include <QObject>

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

{

QApplication a(argc, argv);

w.resize(300,400);

QPixmap birding = QPixmap(QString::fromUtf8(":/butterfly2.PNG")).scaled(40,40);

bird_1->setPixmap(birding);

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

anim1->setDuration(2000);

anim1->setStartValue(QPoint(0,360));

anim1->setEndValue(QPoint(110,180));

anim1->setEasingCurve(QEasingCurve::OutBounce);

//   // anim1->start();

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

QLabel *bird_2 = new QLabel(&w);

bird_2->setPixmap(QPixmap(":/butterfly1.PNG").scaled(40,40));

//    QSequentialAnimationGroup group;//串行动画组

QParallelAnimationGroup group;//并行动画组

group.addAnimation(anim1);

group.addAnimation(anim2);

group.start();

w.show();

return a.exec();
