I need to repeat this. I'm still lost.
here is my code (child is always NULL):
voidDataPointTreeView::mousePressEvent(QMouseEvent*event)
{
QTreeView::mousePressEvent(event);
QModelIndex mi = indexAt(event->pos());
QWidget *child = indexWidget(mi);
//QWidget *child = static_cast<QWidget*>(childAt(event->pos()));
if (!child)
return;
m_dragOffset = event->pos() - child->pos();
}
Are you even using widgets for your items? I mean: do you call
setIndexWidget anywhere? If not, perhaps you should check what
indexWidget() actually returns?

*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.
