QT中treeWidgetItem使用

{
    ui->setupUi(this);

    ui->treeWidget->setHeaderLabels(QStringList()<<"英雄姓名"<<"英雄介紹");  //添加頭項
    QStringList l,m,f;     //相當於C++中  list<string> l
    l<<"力量";
    m<<"敏捷";
    f<<"防禦";
    QTreeWidgetItem *LL= new QTreeWidgetItem(l);   //創建樹項
    QTreeWidgetItem *MM= new QTreeWidgetItem(m);
    QTreeWidgetItem *FF= new QTreeWidgetItem(f);
    ui->treeWidget->addTopLevelItem(LL);//添加
    ui->treeWidget->addTopLevelItem(MM);
    ui->treeWidget->addTopLevelItem(FF);
    QStringList ll,mm,ff;
    ll<<"力量狗";
    mm<<"敏捷狗";
    ff<<"防禦狗";
    QTreeWidgetItem *LLL= new QTreeWidgetItem(ll);
    QTreeWidgetItem *MMM= new QTreeWidgetItem(mm);
    QTreeWidgetItem *FFF= new QTreeWidgetItem(ff);
    LL->addChild(LLL);//添加子項
    MM->addChild(MMM);
    FF->addChild(FFF);
