Qt QTreeWidget - 禁用单个列的交互 [英] Qt QTreeWidget - disabling interaction for a single column
问题描述
是否有一种方法可以禁用交互或只是对 QTreeWidget
中的特定行进行排序?我有一个表,其中如果您单击标题,它排序项目。我有一个自定义 CTreeWidgetItem
其中我已经重载< operator
对我的数据执行自定义排序。问题是,它排在我点击的每个标题,而不只是第一列。我需要它只工作在第一列。是否有我可以做的事?
is there a way to disable interaction or just sorting for a specific row in a QTreeWidget
? I have a table where if you click the header, it sorts the items. I have a custom "CTreeWidgetItem
" where I have overloaded the < operator
to perform a custom sort on my data. The problem is, it sorts on every header I click, not just the first column. I need it to only work for the first column. Is there something I can do?
推荐答案
只需连接到 sectionClicked()
标题的信号( QTreeView: :header()
)。然后将排序指示器强制回到第一部分 QHeaderView :: setSortIndicator()
。
Simply connect to the sectionClicked()
signal of the header (QTreeView::header()
). Then force the sort indicator back to the first section QHeaderView::setSortIndicator()
.
