QT动画渐退

void QNotifyMsgBox::HideAction()

{

    qDebug() << "HideAction";

            //  动画管理器

    m_pAnimation = new QPropertyAnimation(this, "windowOpacity");

    m_pAnimation->setDuration(QNotifyMsgBoxHideDurationTime);

    m_pAnimation->setStartValue(1);

    m_pAnimation->setEndValue(0);

    connect(m_pAnimation, SIGNAL(finished()), this, SLOT(OnHideWin()));

    m_pAnimation->start(QAbstractAnimation::DeleteWhenStopped);

}

void QNotifyMsgBox::OnHideWin()

{

    qDebug() << "OnHideWin";

    m_pAnimation->stop();

    m_pAnimation = NULL;

    this->hide();

}

动画暂停与继续

// 鼠标移出信号

void QNotifyMsgBox::leaveEvent(QEvent* )

{

    qDebug() << "leaveEvent";

    if (m_pAnimation)

    {

        m_pAnimation->pause();

        m_pAnimation->resume();

    }

}
