QStackedLayout布局怎么控制大小？用QStackedLayout导致界面变形。

我想实现第一个图的效果，但是用QStackedLayout做出来的效果，却是第二个的，请问这是怎么回事啊？

代码如下：

pauseTimeButton = new QPushButton(tr("暂停"),this);

   pauseTimeButton->setFixedSize(40,23);

   resetTimeButton = new QPushButton(tr("重置"),this);

   resetTimeButton->setFixedSize(40,23);

   timeStackedLayout = new QStackedLayout;

   //timeStackedLayout->setMargin(0);

   //timeStackedLayout->setSpacing(0);

   timeStackedLayout->addWidget(pauseTimeButton);

   timeStackedLayout->addWidget(resetTimeButton);

   //qDebug() << timeStackedLayout->minimumSize();

   //QGroupBox *stackedGroupBox = new QGroupBox(this);

   //stackedGroupBox->setStyleSheet("border-style:hidden");

   //stackedGroupBox->setFixedSize(43,25);

   //stackedGroupBox->setLayout(timeStackedLayout);

   resetTimeButton->setVisible(false);

   QHBoxLayout *dateTimeLayout = new QHBoxLayout;

   dateTimeLayout->setMargin(5);

   dateTimeLayout->setSpacing(0);

   dateTimeLayout->addStretch(2);

   dateTimeLayout->addWidget(dateLabel);

   dateTimeLayout->addStretch(1);

   dateTimeLayout->addWidget(dateEditWidget);

   dateTimeLayout->addStretch(2);

   dateTimeLayout->addWidget(timeLabel);

   dateTimeLayout->addStretch(1);

   dateTimeLayout->addWidget(timeEditWidget);

   dateTimeLayout->addStretch(2);

   dateTimeLayout->addWidget(weekComboBox);

   dateTimeLayout->addStretch(1);

   //dateTimeLayout->addWidget(stackedGroupBox);

   dateTimeLayout->addLayout(timeStackedLayout);

   //dateTimeLayout->addWidget(pauseTimeButton);

   //dateTimeLayout->addWidget(resetTimeButton);

   dateTimeLayout->addStretch(2);

   QGroupBox *dateTimeGroupBox = new QGroupBox(this);

   dateTimeGroupBox->setFixedHeight(35);

   dateTimeGroupBox->setLayout(dateTimeLayout);

   connect(pauseTimeButton,SIGNAL(clicked()),this,SLOT(pauseTimeButtonClicked()));

   connect(resetTimeButton,SIGNAL(clicked()),this,SLOT(resetTimeButtonClicked()));

我怀疑，是按钮在加入QstackedLayout的时候，还是默认的大小（75,23），所以会导致照不齐的结果。。。。求指导
