슬라이서는 다음 단계에 따라 GeneralSlicerData와 함께 작동합니다:
데이터로 새 GeneralSlicerData를 만듭니다.
새 사용자 정의 슬라이서를 만들고 GeneralSlicerData에 연결합니다.
GeneralSlicerData에서 열 데이터를 가져와서 슬라이서 UI를 작성합니다.
UI 이벤트에 응답하고 GeneralSlicerData doFilter 메서드를 호출합니다.
GeneralSlicerData에서 필터링된 결과를 가져와서 슬라이서 UI를 업데이트합니다.
다음 API는 간단한 코드를 작성하는 데 도움이 됩니다:
getData: 지정된 열의 모든 데이터를 가져옵니다.
getExclusiveData: 지정된 열의 독점 데이터(비반복 데이터)를 가져옵니다.
doFilter: 지정된 열 및 독점 데이터 인덱스에 해당하는 데이터를 필터링합니다.
doUnfilter: 지정된 열에 해당하는 데이터의 필터링을 해제합니다.
attachListener: 슬라이서 데이터에 슬라이서를 연결합니다.
detachListener: 슬라이서 데이터에서 슬라이서를 분리합니다.
onFiltered: 슬라이서 데이터가 필터링된 후에 발생합니다.
