I'm not sure if thats really needed, never created itemviews that can do
drag and drop. The puzzle example indicates however that you don't need
to change the listviews, only the underlying model which needs to
provide mimeData and dropMimeData and probably also mimeTypes. Then you
just need to enable the drag/drop on the listviews by setting their dnd
properties to true.

You should never try to alter the generated code. If a subclass is
really needed you should create a new widget class and use the promoting
feature to have code generated that uses your new widget. See the
designer documentation for how that works.


Future looks spotty.  You will spill soup in late evening.
