    QSplitter *splitterMain = new QSplitter(Qt::Horizontal, this);
    QTextEdit *textLeft     = new QTextEdit(QObject::tr("Left Widget"), splitterMain);
    textLeft->setAlignment(Qt::AlignCenter);

    //设置右分割窗体
    QSplitter *splitterRight = new QSplitter(Qt::Vertical, splitterMain);
    QTextEdit *textUp        = new QTextEdit(QObject::tr("Top Widget"), splitterRight);
    textUp->setAlignment(Qt::AlignCenter);

    QTextEdit *textBottom    = new QTextEdit(QObject::tr("Bottom Widget"), splitterRight);
    textBottom->setAlignment(Qt::AlignCenter);

    //设置拉伸比例
    splitterMain->setStretchFactor(1,1);


    this->setCentralWidget(splitterMain);
