I have a QListView in my GUI. I would like to be able to use Drag-N-Drop to
allow the user to move items with the list. I have checked some settings in
QDesigner to enable this functionality but the issue I am having is that if the
user drags a selection directly over another entry then the entry that got
dropped on is removed and the selected item that was being dragged is put in
its place. Is there a way (without subclassing a custom Model) to disable the
dropping of one item on another?
I am currently using a QStringListModel and it looks I need to subclass that
model and implement the flags() method?
Qt::ItemFlags DragDropListModel::flags(const QModelIndex &index) const
{
Qt::ItemFlags defaultFlags = QStringListModel::flags(index);
if (index.isValid())
return Qt::ItemIsDragEnabled | defaultFlags;
else
return Qt::ItemIsDropEnabled | defaultFlags;
}
Is this a correct understanding of the situation?
Thanks
Mike Jackson
