[Interest] Getting QTreeView item click offset for DnD

[Jason H]

I need to repeat this. I'm still lost.
here is my code (child is always NULL):

voidDataPointTreeView::mousePressEvent(QMouseEvent*event) 
{
QTreeView::mousePressEvent(event);
QModelIndexmi=indexAt(event->pos());
QWidget*child=indexWidget(mi);
//QWidget*child=static_cast<QWidget*>(childAt(event->pos()));
if(!child)
return;

m_dragOffset=event->pos()-child->pos();
}

Subject: [Interest] Getting QTreeView item click offset for DnD
 

I need to drag model items from a QTreeView to a widget and make the item appear in the widget at the right spot.
I have it working except that the drop is not exact. It is off by where the user clicked in the QStandardItem.
I need to figure out how to get that click offset (i.e. QPoint(50,10)) and factor that into the drop location (i.e move(event->pos()-clickOffset);)

What do I need to do to get that click offset inside the QTrreeView?

Thanks.
