Return value of QHeaderView ::logicalIndexAt is not accurate

jronald

code as below, what's the bug?

void MyTreeView::OnHeaderViewMouseRClick(bool checked)
{
    QHeaderView * hv = header();

    QPoint pt = QCursor::pos();

    pt = hv->mapFromGlobal(pt);

    int logical_index = hv->logicalIndexAt(pt);
    QString s = QString::asprintf("%d", logical_index);

    QMessageBox::information(this, "info", s);
}

I've found the cause of the problem, mouse position when clicking on a menu item is different from the mouse position when popping up the context menu.

Hi,

What's the values you get ?
What's the values you expect ?

The red sections and indexes are what's I got.
The green sections and indexes are what's expected.

You should print out pt - I would guess x is not 0 when you click on the very left side of the header view.
