QTreeWidget - itemAt(QMousePos): error if there is a header

[wysota]

Why are you trying to get a global position? You don't need a global position but position in the viewport's coordinate space.

This should work:

QPoint pos = ui->treeWidget->viewport()->mapFromParent(event->pos());

QPoint pos = ui->treeWidget->viewport()->mapFromParent(event->pos());

To copy to clipboard, switch view to plain text mode 

or something like that, depending on what is the receiver of the event.
