There are three types of data reference items:
- Single Data Reference Item
- Group Data Reference Item
- Definition Data Reference Item
Single Data Reference Item
In the Screen Painter, widget event signals can be linked to
a data reference move. With the prefix D:GET:data_ref
a value will be moved FROM the single data reference TO
the screen widget. With the prefix D:PUT:data_ref
a value will be moved TO the single data reference FROM
the screen widget.
