void ValueDelegate::setEditorData ( QWidget *  editor, const QModelIndex &  index  ) const

virtual

Initialise the editor with data from model, unless there is a previous error in edition of this item, and it is the first initialisation of the editor: in case of error, a new editor must be initialised with the wrong edited string, for correction.

If edition is in error, keep the wrong string value in a map, to initialise a next instance of editor with the wrong string, in order to help correction of the edition.
