Hi, I have a problem with QTreeWidget with function itemAt(QMousePos). If there is a header in tree widget then function returns next item. Is it a bug? :confused:

Post a minimal compilable code reproducing the problem :)

No, it's not a bug. The coordinates are in viewport space not the view space.

I can not figured it out.

I use it this way now, but it is not working with header:



// without header works fine
QMouseEvent *MousePos; // where the user clicked
treeWidget->itemAt(MousePos->pos())

// with header, try to get global position but never returns item
QMouseEvent *mouseEvent = static_cast<QMouseEvent*> (event);
QPoint globalPos = ui->treeWidget->viewport()->mapToGlobal(mouseEvent->pos());
QTreeWidgetItem *item = ui->treeWidget->itemAt(globalPos);



fuck, nothing works :mad:

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());

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