콤보 상자 셀을 만들려면 다음 예를 따르십시오:
editorValueType 메서드를 사용하여 기본 데이터 모델에 기록된 값을 가져오고 설정할 수 있습니다. 편집기 값 유형은 EditorValueType 열거입니다.
text: 선택된 항목의 텍스트 값을 모델에 씁니다.
index: 선택된 항목의 색인을 모델에 씁니다.
value: 선택된 항목의 해당 데이터 값을 모델에 씁니다.
다른 editorValueType 설정은 다른 유형의 편집기 값을 만듭니다. 콤보 상자의 값은 콤보 상자의 드롭다운 목록 항목에 따라 다릅니다. items 메서드를 사용하여 항목을 가져오고 설정할 수 있습니다. 예:
dataBinding 메서드를 사용하여 콤보 상자를 데이터 소스에 바인딩할 수도 있습니다. 데이터 소스는 런타임에 콤보 상자의 항목을 대체합니다. 예를 들어:
editable 메서드를 사용하여 사용자가 콤보 상자 편집기에 입력할 수 있는지 여부를 설정합니다. 기본값은 false입니다. 선택만 허용됩니다. 예:
itemHeight 메서드를 사용하여 드롭다운 목록에서 각 항목의 높이를 설정할 수 있습니다. 예:
allowFloat 메서드를 사용해 드롭다운 목록이 Spread 외부에 떠 있도록 허용할지 설정하십시오.
