QTtreeview使用

QStandardItemModel* model = new QStandardItemModel(ui.treeView);
ui.treeView->setModel(model);
ui.treeView->setEditTriggers(0); //将节点的显示信息设置为不可编辑的状态
model->setHorizontalHeaderLabels(QStringList()<<"Device"); //添加表头信息

QStandardItem* itemProject = new QStandardItem("10.18.147.31");创建父节点
model->setItem(0,0,itemProject);
QStandardItem* itemChild = new QStandardItem("Camera1"); //添加子节点信息
model->setItem(1,0,itemProject);
itemProject->appendRow(itemChild);


QTreeWidgetItem *imageItem1 = new QTreeWidgetItem();
imageItem1->setText(0,"123");

QTreeWidgetItem *cities = new QTreeWidgetItem(ui.treeWidget);
cities->setText(0, tr("10.18.136.212"));
QTreeWidgetItem *osloItem = new QTreeWidgetItem(cities);
osloItem->setText(0, tr("Camera1"));
osloItem->setText(1, tr("Yes"));
