QTableView prevent internal movement

Toby

Hi guys

i have implemented a Drag/Drop inside a subclassed QAbstractTableModel.
It works perfectly if i move stuff from one table to another:

removeRows gets called at the sourcemodel -> Job Done

But in case i move a row inside the table, it gets cloned, because:

removeRows isn't called, moveRows isn't called either.

How can i implement a working move inside the same table
OR
prevent "internal movement" ?

greetings

Don't know if that is a good solution, but i found one:

bool MyModel::canDropMimeData( const QMimeData *data, Qt::DropAction action, int, int, const QModelIndex & ) const
{
    if ( action != Qt::MoveAction )
        return false;
    auto m = dynamic_cast<const UserDefinedMimeData*> ( data );
    if ( !m )
        return false;
    return m->sender() != this;
}

I am using a subclassed QMimeData anyway, so i added a const-Pointer to the sourcemodel to the Mimedata and compared that pointer inside "canDropMimeData()" of the destinationmodel with "this". If they are equal the drop is blocked.
