The right way should be implementing QAbstractItemModel for the queue (with drag&drop methods) and then the GUI would automatically support it with none or minimal changes. Similar to what Bart said, we prefer using the .ui files as much as possible. Also, when the QAbstractItemModel approach is used, there should be no need to split the patch into 2 review requests.

I didn't even consider what the patch is actually supposed to do. Not completely sure that a QAIM subclass is the best option. D'n'D for moving is a bit harder then regular dropMimeData. But a model for a list of simple list of tracks that can be ordered like that could be reused a lot, even after the big PlaylistQueue refactor.

On successful dropEvent a signal is emitted, which is intercepted by a new slot reloadQueue() in PlaylistQueueEditor. This slot in turn recreates the queue via The::playlistActions().
