QTreeWidget

m_treeWidget = new QTreeWidget;//表头可双击的m_treeWidget->header()->setClickable(true);//可排序的m_treeWidget->setSortingEnabled(true);//m_treeWidget->sortItems(3, Qt::AscendingOrder);//排序图标m_treeWidget->header()->setSortIndicatorShown(true);//表头标签居中m_treeWidget->headerItem()->setTextAlignment(0, Qt::AlignHCenter);m_treeWidget->headerItem()->setTextAlignment(1, Qt::AlignHCenter);m_treeWidget->headerItem()->setTextAlignment(2, Qt::AlignHCenter);m_treeWidget->headerItem()->setTextAlignment(3, Qt::AlignHCenter);m_treeWidget->headerItem()->setTextAlignment(4, Qt::AlignHCenter);//第0列为ID,隐藏,这样也可以使Tree更像是tablem_treeWidget->header()->hideSection(0);m_treeWidget->header()->hideSection(1);//第1列为序号,固定列宽m_treeWidget->header()->setResizeMode(1, QHeaderView::ResizeToContents );//单行选择m_treeWidget->setSelectionMode(QAbstractItemView::SingleSelection);m_treeWidget->setHeaderLabels(QStringList()<<QString("ID")<<QString("序号")<<QString("数据名称")<<QString("上传时间")<<QString("上传者")<<QString("IP地址")<<QString("描述"));

添加Item很方便

QStringList strlist;类型

m_treeWidget->addTopLevelItem(new QTreeWidgetItem(strlist));
