Qt QTreeWidget - disabling interaction for a single column

Question

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?

Answer 1

Simply connect to the sectionClicked() signal of the header (QTreeView::header()). Then force the sort indicator back to the first section QHeaderView::setSortIndicator().
