Qt анимация диалога c++

Хочу сдедать диалог который будет выпадать с помощью анимации
Анимация готова но я не знаю как попровать ее так чтобы мой диалог выезжал с верху на центр, при закрытии диалог заезжает наверх

первый класс 

void ConnectionEditor::setupPoint()
{
    if(pAdder.state) return;
    auto *pin = qobject_cast<PinPoint*>(sender());
    auto *dialog = new ConfigDialog(pin, &pin->getConnection(), this->parentWidget());
   // dialog->setAttribute(Qt::WA_DeleteOnClose, true);
    dialog->open();

    connect(dialog, &ConfigDialog::finished, [=] {});
}


QWidget *ConnectionEditor::getView()
{
    return this;
}




второй класс    







void ConfigDialog::open()

{
    animate(false);
    QDialog::open();
}

void ConfigDialog::done(int r)
{
    if (!animation_on) {
        animate(true);
        setResult(r);
        if (r == QDialog::Accepted)
            emit accepted();
        else if (r == QDialog::Rejected)
            emit rejected();

        emit finished(r);
    }
}

void ConfigDialog::animate(bool reverse)
{

    Animator::dialogAnimation(this);

    if (!reverse) {

        Animator::dialogAnimationIfReverse(this, 0.0, 1.0);

    } else {

        emit reverseAnimStarted();

        Animator::dialogAnimationIfElse(this, 1.0, 0.0, 1000, 1500 );
    }

}






третий класс









    void Animator::dialogAnimation(QWidget *widget)
    {
        auto animFade= new QPropertyAnimation(widget, "windowOpacity", widget);
        animFade->setDuration(1500);
        animFade->setEasingCurve(QEasingCurve::Linear);

        auto pos1 = widget->mapToParent(widget->rect().topLeft());
        auto pos2 = QPoint(pos1.x(), -widget->height());


        auto animMove = new QPropertyAnimation(widget, "pos", widget);
        animFade->setDuration(1500); 
        animMove->setEasingCurve(QEasingCurve::OutQuad);

    }

    void Animator::dialogAnimationIfReverse(QWidget *widget, const QVariant StartVal1, const QVariant EndVal2)
    {
        auto pos1 = widget->mapToParent(widget->rect().topLeft());

        auto animMove = new QPropertyAnimation(widget, "pos", widget);
        animFade->setStartValue(StartVal1);
        animFade->setEndValue(EndVal2);
        animMove->setStartValue(pos2);
        animMove->setEndValue(pos1);
    }

    void Animator::dialogAnimationIfElse(QWidget *widget, const QVariant  StartVal1, const QVariant EndVal2, int timeInMS1, int timeInMS2)
    {
        auto pos1 = widget->mapToParent(widget->rect().topLeft());
        auto pos2 = QPoint(pos1.x(), -widget->height());

        {
            animFade->setDuration(timeInMS1);
            animMove->setDuration(timeInMS2);
            animFade->setStartValue(StartVal1);

            animMove->setStartValue(pos1);
            animMove->setEndValue(pos2);

            QObject::connect(animFade, &QPropertyAnimation::finished,
            [widget] { widget->hide(); });

        }

        animFade->start(QAbstractAnimation::DeleteWhenStopped);
        animMove->start(QAbstractAnimation::DeleteWhenStopped);
    }


    void Animator::StartConfidDialog(QWidget *widget, const QVariant  StartVal1, const QVariant EndVal2, int timeInMS1, int timeInMS2)

    {
        auto pos1 = widget->mapToParent(widget->rect().topLeft());
        auto pos2 = QPoint(pos1.x(), -widget->height());
        auto animFade= new QPropertyAnimation(widget, "windowOpacity", widget);
        auto animMove = new QPropertyAnimation(widget, "pos", widget);
        {
            animFade->setDuration(timeInMS1);
            animMove->setDuration(timeInMS2);

            QObject::connect(animFade, &QPropertyAnimation::finished,

        }

        animFade->start(QAbstractAnimation::DeleteWhenStopped);
        animMove->start(QAbstractAnimation::DeleteWhenStopped);
    }


    void Animator::startdialogAnimation(QWidget *widget)
    {
