[提问]QTreeWidget如何得到行号？ [复制链接]

帮助文档提示：


QTreeWidgetItem * QTreeWidget::takeTopLevelItem ( int index )


Removes the top-level item at the given index in the tree and returns it, otherwise returns 0;
See also insertTopLevelItem(), topLevelItem(), and topLevelItemCount().

QTreeWidgetItem * QTreeWidget::topLevelItem ( int index ) const


Returns the top level item at the given index, or 0 if the item does not exist.
See also topLevelItemCount() and insertTopLevelItem().



具体怎么得到，如双击treeWidgt:


void MySoft::on_treeWidget_itemDoubleClicked(QTreeWidgetItem *item, int column)
{    
     //怎么得到双击的item的行号呢？
}
谢谢解答。

查到一些说用int indexOfTopLevelItem ( QTreeWidgetItem * item ) const

这样用后：

void Mysoft::on_treeWidget_itemDoubleClicked(QTreeWidgetItem *item, int column)

{
  int itemRow = indexOfTopLevelItem(item);

}

编译提示：
错误:'indexOfTopLevelItem' was not declared in this scope

ui->treeWidget->currentIndex().row();

多行怎么区分呢？

对子节点再进行判断，判断是否有子节点。同时再判断是否有parent

自己遍历树 计算
