QSplitter-窗口分割器 - 拉伸控件

想要实现主窗口内的控件可以跟随鼠标随意拉伸缩放，可以通过该控件实现。

 /***3.先水平，后垂直****/
    QHBoxLayout *pHBox = new QHBoxLayout(this);

    QSplitter *pSplitter = new QSplitter(Qt::Orientation::Horizontal, this);//水平
    pSplitter->setStyleSheet("QSplitter:handle{background-color:grey}");
    QLabel* labelFile = new QLabel("文件目录：");
    QLineEdit* lineFile = new QLineEdit("路径");
    labelFile->setFixedSize(60,30);
    lineFile->setFixedHeight(30);
    pSplitter->addWidget(labelFile);
    pSplitter->addWidget(lineFile);

    QSplitter *pSplitter1 = new QSplitter(Qt::Orientation::Horizontal, this);//水平
    pSplitter1->addWidget(new QTreeWidget());
    pSplitter1->addWidget(new QTreeWidget());
    pSplitter1->setStretchFactor(0,2);
    pSplitter1->setStretchFactor(1,4);

    QSplitter *pSplitter2 = new QSplitter(Qt::Orientation::Horizontal, this);//水平
    QLabel* labelFileName = new QLabel("文件名字：");
    QLineEdit* lineFileName = new QLineEdit("路径1");
    labelFileName->setFixedSize(60,30);
    lineFileName->setFixedHeight(30);
    pSplitter2->addWidget(labelFileName);
    pSplitter2->addWidget(lineFileName);

    QSplitter *pSplitter3 = new QSplitter(Qt::Orientation::Horizontal, this);//水平
    QLabel* labelFileType = new QLabel("文件类型：");
    QLineEdit* lineFileType = new QLineEdit("路径2");
    labelFileType->setFixedSize(60,30);
    labelFileType->setFixedHeight(30);
    pSplitter3->addWidget(labelFileType);
    pSplitter3->addWidget(lineFileType);

    QSplitter *pSplitterV = new QSplitter(Qt::Orientation::Vertical, this);//垂直
    pSplitterV->addWidget(pSplitter);
    pSplitterV->addWidget(pSplitter1);
    pSplitterV->addWidget(pSplitter2);
    pSplitterV->addWidget(pSplitter3);

    pHBox->addWidget(pSplitterV);

效果图

其中可以设置比例：setStretchFactor方法

 QSplitter *pSplitter1 = new QSplitter(Qt::Orientation::Horizontal, this);//水平
    pSplitter1->addWidget(new QTreeWidget());
    pSplitter1->addWidget(new QTreeWidget());
    pSplitter1->setStretchFactor(0,2);
    pSplitter1->setStretchFactor(1,4);
