Qt学习之QTreeWidget、QTableWidget

 1、新建一个空的QWidget类型的项目，按下图添加两个部件如下：

 2、在Widget类构造函数中添加如下代码：

    // treeWidget设置
    ui->treeWidget->setHeaderLabels(QStringList()<<"陕西前10强公司简介");

    QTreeWidgetItem *gsItem = new QTreeWidgetItem(QStringList()<<"陕西JD公司");

    ui->treeWidget->addTopLevelItem(gsItem);

    QTreeWidgetItem *yfItem = new QTreeWidgetItem(QStringList()<<"研发中心");
    QTreeWidgetItem *csItem = new QTreeWidgetItem(QStringList()<<"测试中心");
    QTreeWidgetItem *cpItem = new QTreeWidgetItem(QStringList()<<"产品中心");

    gsItem->addChild(yfItem);
    gsItem->addChild(csItem);
    gsItem->addChild(cpItem);

    QTreeWidgetItem *yfItem_lijd = new QTreeWidgetItem(QStringList()<<"李建东");
    QTreeWidgetItem *yfItem_lidh = new QTreeWidgetItem(QStringList()<<"刘德华");

    yfItem->addChild(yfItem_lijd);
    yfItem->addChild(yfItem_lidh);

    QTreeWidgetItem *csItem_lcw = new QTreeWidgetItem(QStringList()<<"梁朝伟");
    QTreeWidgetItem *csItem_gfc = new QTreeWidgetItem(QStringList()<<"郭富城");
    csItem->addChild(csItem_lcw);
    csItem->addChild(csItem_gfc);

    QTreeWidgetItem *cpItem_lim = new QTreeWidgetItem(QStringList()<<"黎明");
    QTreeWidgetItem *cpItem_wuj = new QTreeWidgetItem(QStringList()<<"吴京");
    cpItem->addChild(cpItem_lim);
    cpItem->addChild(cpItem_wuj);

    // tableWidget设置
    ui->tableWidget->setColumnCount(4);
    ui->tableWidget->setHorizontalHeaderLabels(QStringList()<<"姓名"<<"性别"<<"年龄");
    ui->tableWidget->setHorizontalHeaderItem(3, new QTableWidgetItem("婚否"));

    ui->tableWidget->setRowCount(4);

    QStringList qSLname;
    qSLname << "李建东" << "刘德华" << "梁朝伟" << "梅艳芳";

    QList<QString> qSLsex, qSLhun;
    qSLsex << "男" << "男" << "男" << "女";
    qSLhun << "已婚" << "已婚" << "未婚" << "已婚";

    for(int i = 0; i < 4; i++)
    {
        ui->tableWidget->setItem(i, 0, new QTableWidgetItem(qSLname[i]));
        ui->tableWidget->setItem(i, 1, new QTableWidgetItem(qSLsex.at(i)));
        ui->tableWidget->setItem(i, 2, new QTableWidgetItem(QString().number(i+12)));
        ui->tableWidget->setItem(i, 3, new QTableWidgetItem(qSLhun[i]));
    }

3、运行结果展示：
