36 //! A ListEditor is an auxiliary operator for Editor/EditForm
37 //! I.E. it works on parameter values expressed as strings
39 //! For a parameter which is a list, it may not be edited in once
40 //! by just setting a new value (as a string)
42 //! Firstly, a list can be long (and tedious to be accessed flat)
43 //! then requires a better way of accessing
45 //! Moreover, not only its VALUES may be changed (SetValue), but
46 //! also its LENGTH : items may be added or removed ...
48 //! Hence, the way of editing a parameter as a list is :
49 //! - edit it separately, with the help of a ListEditor
50 //! - it remains possible to prepare a new list of values apart
51 //! - then give the new list in once to the EditForm
53 //! An EditList is produced by the Editor, with a basic definition
54 //! This definition (brought by this class) can be redefined
55 //! Hence the Editor may produce a specific ListEditor as needed
