Qt动态靠边收起速度越来越快

}

void Box::leaveEvent(QEvent *)

rc.setRect(rect.x(),rect.y(),rect.width(),rect.height());
QObject::connect(hideTimer, SIGNAL(timeout()), this, SLOT(hideSlot()));

hideTimer->start(30);
}

void Box::hideSlot()
{
rect = this->geometry();
rc.setRect(rect.x(),rect.y(),rect.width(),rect.height());
move(rc.x(),rc.y() - 3);
if(rect.y() + rect.height() < 40)
hideTimer->stop();
}

void Box::showSlot()
{
rect = this->geometry();
rc.setRect(rect.x(),rect.y(),rect.width(),rect.height());
move(rc.x(), rc.y() + 1.5);
if(rect.y() > 0)
showTimer->stop();
}

为什么收起和显示的速度随着操作次数的增多越来越快，求解。

我猜测是不是操作系统的优化。。。。。
