Treewidget节点的增加

父节点的创建

// 隐藏QTreewidget标题头

ui->treeWidget->header()->hide();

// 实现Treewidget父节点的挂载

// 创建存放QTreewidget的容器

QList<QTreeWidgetItem*>lsTree;

QTreeWidgetItem *pTreewidget = new QTreeWidgetItem();

pTreewidget->setText(0,"column1");

lsTree.push_back( pTreewidget);

pTreewidget = new QTreeWidgetItem();

pTreewidget->setText(0,"column2");

lsTree.push_back( pTreewidget);

ui->treeWidget->addTopLevelItems(lsTree);

子节点的挂载

// 子节点的挂载 新手版

QTreeWidgetItem *pChild = new QTreeWidgetItem();

pChild->setText(0,"child1");

pTreewidget->addChild(pChild);

pChild = new QTreeWidgetItem();

pChild->setText(0,"child2");

pTreewidget->addChild(pChild);

// 子节点挂载进阶版

// 先创建一个存放某节点孩子的容器 例如节点二

QList<QTreeWidgetItem*>pNodeTwoChildren;

// 开始挂载

QTreeWidgetItem *pTree = new QTreeWidgetItem();

pTree->setText(0,"Child1");

pNodeTwoChildren.push_back(pTree);

pTree = new QTreeWidgetItem();

pTree->setText(0,"Child2");

pNodeTwoChildren.push_back(pTree);

pTreewidget->addChildren(pNodeTwoChildren);
