I want to animate an object with to different QPropertyAnimations. The code works fine (animates as wanted) but I´m producing a memoryleak and don´t really know how to handle it. I tried to use QSignalMapper but that doesn´t help.

First of all my code:
@
void MyClass::MyClass()
{
m_signalMapper = new QSignalMapper(this);
connect(m_signalMapper, SIGNAL(mapped(QObject*)), this, SLOT(DeleteAnimation(QObject*)));
}

void MyClass::StartAnimation()
{
QPropertyAnimation *ani = new QPropertyAnimation(myObject,"pos");
ani->setDuration(300);
ani->setStartValue(QPoint(myX, myY));
ani->setEndValue(QPoint(myX, myY+ 50));
ani->setEasingCurve(QEasingCurve::InCurve);
m_signalMapper->setMapping(ani, ani);
connect(ani, SIGNAL(finished()),m_signalMapper, SLOT(map()));
ani->start();

    QPropertyAnimation *secondani = new QPropertyAnimation(myObject,"opacity");
    secondani->setDuration(800);
    secondani->setStartValue(1.0);
    secondani->setEndValue(1.5);
    secondani->setEasingCurve(QEasingCurve::InCurve);
    m_signalMapper->setMapping(secondani , secondani );
    connect(secondani , SIGNAL(finished()),m_signalMapper, SLOT(map()));
    secondani->start();

}

void MyClass::DeleteAnimation(QObject *sender)
{
QPropertyAnimation ani = qobject_cast <QPropertyAnimation>(sender);
disconnect(ani, SIGNAL(finished()), this, 0);

    ani->stop();
    delete ani;
    ani = NULL;

}

If the animations are finished "DeleteAnimation()" is called. But the pointer to the object is always the pointer to "secondani". "secondani" is deleted correctly "ani" will never be deleted.

I tried with start(QPropertyAnimation::DeleteWhenStopped) but that doesn´t work. Connecting the animations directly to "DeleteAnimation()" without using the Signalmapper also doesn´t work. Could someone give me a hint how to do it better?

To detected the leaks I used VLD.

Thanks and regards
