QT QSplitter設置初始比例setStretchFactor失效解決

QSplitter如下為常用 設置顯示比例

1 pRightSplitter=new QSplitter(Qt::Vertical);
2 pRightSplitter->setMouseTracking(true);
3 pRightSplitter->setStretchFactor(0,8);
4 pRightSplitter->setStretchFactor(1,2);
但是由於內部有子窗口的布局時，會失效

使用下面方法設置

1 //pRightTopWidget 為子窗口1
2 QSizePolicy rightTopPolicy = pRightTopWidget->sizePolicy();
3 rightTopPolicy.setVerticalStretch(8);
4 pRightTopWidget->setSizePolicy(rightTopPolicy);
5 //pRightDownWidget 為子窗口2
6 QSizePolicy rightDownPolicy = pRightDownWidget->sizePolicy();
7 rightDownPolicy.setVerticalStretch(2);
8 pRightDownWidget->setSizePolicy(rightDownPolicy);
