一、設(shè)置列的寬度 、數(shù)量
setColumnCount(1); //數(shù)量 setColumnWidth(0,100); //寬度二、添加信息QTreeWidgetItem* item = new QTreeWidgetItem(ui.treeWidget);item->setText(0,"nihao");item->setText(1,"nihao");ui.treeWidget->addTopLevelItem(item);三、移除指定項(xiàng)的信息int row = ui.treeWidget->currentIndex().row(); //currentIndex() 獲取當(dāng)前索引 ui.treeWidget->takeTopLevelItem(row); //takeTopLevelItem() 清除獲取頂級(jí)項(xiàng)四、按指定列排序void QTreeWidget::sortItems(int column, Qt::SortOrder order)enum Qt::SortOrder
Qt::AscendingOrder升序 Qt::DescendingOrder 降序
五、獲取指定項(xiàng)的信息
QTreeWidgetItem*item = ui.treeWidget->currentItem(); //獲取當(dāng)前項(xiàng)
item->text(0) //第一個(gè)值
六、設(shè)置標(biāo)題
ui.treeWidget->setHeaderLabels(QStringList() << QString::fromLocal8Bit("節(jié)數(shù)") << QString::fromLocal8Bit("時(shí)間"));
