右鍵屬性修改QTreeWidget

    rootItem=new QTreeWidgetItem(ui->treeWidget,QStringList(QString(prjName)));//添加節點  
     rootItem->setFlags(rootItem->flags() | Qt::ItemIsEditable);//支持重命名

void SlotRenameItem(QString prjName,QString prjPath) {
    QTreeWidgetItem* item=ui->treeWidget->currentItem();   
    item->setText(0,prjName);
}
