QT QSplitter设置初始比例setStretchFactor失效解决

QSplitter如下为常用 设置显示比例

     pRightSplitter=new QSplitter(Qt::Vertical);
     pRightSplitter->setMouseTracking(true);
     pRightSplitter->setStretchFactor(,);
     pRightSplitter->setStretchFactor(,);

但是由于内部有子窗口的布局时，会失效

使用下面方法设置

 //pRightTopWidget 为子窗口1
 QSizePolicy rightTopPolicy = pRightTopWidget->sizePolicy();
 rightTopPolicy.setVerticalStretch();
 pRightTopWidget->setSizePolicy(rightTopPolicy);
 //pRightDownWidget 为子窗口2
 QSizePolicy rightDownPolicy = pRightDownWidget->sizePolicy();
 rightDownPolicy.setVerticalStretch();
 pRightDownWidget->setSizePolicy(rightDownPolicy);
