RecordGrid で オートコンプリート

[umemura]

Curl EXT でオートコンプリートが用意されていますが、これをRecordGrid で実現するにはどうすればいいのでしょうか。

AutocompleteStringCell を cell-spec に渡せば、そのカラムのデータがコンプリートの対象になりますが、
事前に用意したデータのリストのみをコンプリートの対象にしたいです。

ちょっと長いけどできました。

Code:

{define-proc public {filter-complete
                        list:StringArray,
                        prefix:String = "",
                        sort?:bool = true,
                        remove-blank?:bool = true
                    }:StringArray
    let values:Set = {Set}                     || Set of unique values
    let value-list:StringArray = {StringArray} || Values in order seen
    {for fv in list do
        {if fv == "" and remove-blank? then
            {continue}
        }
        {if not {values.member? fv} and
            {fv.prefix? prefix, ignore-case? = true}
         then
            {value-list.append fv}
            {values.insert fv}
        }
    }
    {if sort? then
        {value-list.sort}
    }
    {return value-list}
}

{define-class public open SimpleStringCellProvider
  {inherits AutocompleteProvider}
  
  field list:StringArray
  field protected cell:RecordGridCell
  
  {constructor public {default
                          cell:RecordGridCell,
                          max-results:int,
                          list:StringArray
                      }
    {construct-super max-results}
    set self.cell = cell
    set self.list = list
  }
  
  {method public open {refresh acf:AutocompleteMixin}:void
    {if-non-null record = self.cell.record then
        {if-non-null rs = record.record-set then
            {acf.populate-from-strings
                {filter-complete
                    self.list,
                    prefix = acf.text-field.value
                }
            }
            {return}
        }
    }
    {acf.populate-from-strings {StringArray}}
  }
}

{define-class public ExAutocompleteStringCell
  {inherits AutocompleteStringCell}
  
  field count:int = 10
  field list:StringArray = {StringArray}
  
  {constructor public {default }
    
  }
  {method public {create-editor}:TextField
    let editor:TextField =
        {super.create-editor} asa TextField
    
    set (editor asa SRGAutocompleteTextField).provider =
        {SimpleStringCellProvider
            self,
            self.count,
            self.list
        }
    {return editor}
  }
}
{define-class public SimpleCompleteCell
  {inherits ExAutocompleteStringCell}
  {constructor public {default }
    set self.list = {StringArray "aaa", "aab", "abb", "abc"}
    
  }
}

ExAutocompleteStringCell を継承して作ったSimpleCompleteCellを、RecordGridcolumn の cell-spec に渡してやればOKでした。
