확대/축소 수행
Ctrl + 마우스 휠
상태 표시줄 확대/축소 표시기
두 손가락으로 작동, 터치식만 가능
sheet.zoom(zoomFactor) API 사용
allowUserZoom의 스프레드 옵션
시트 뷰포트의 확대/축소 여부를 제어하는 스프레드 옵션을 제공합니다.
API를 통해 확대/축소 배율을 가져오거나 설정합니다.
ViewZooming / ViewZoomed 이벤트
서로 다른 워크시트/ 스프레드 인스턴스의 확대/축소 프로세스에 개입하기 위해 두 가지 이벤트를 제공합니다.
GC.Spread.Sheets.Events.ViewZooming
handler 함수에 사용할 수 있는 인수는 다음과 같습니다.
sheet: 이벤트를 트리거한 시트
sheetName: 시트의 이름
newZoomFactor: 새로운 확대/축소 배율, 사용자는 실제 확대/축소 액션을 간섭하기 위해 약간의 변경을 할 수 있습니다.
oldZoomFactor: 이전 확대축소 배율
cancel: 작업을 취소할지 여부를 나타내는 값
GC.Spread.Sheets.Events.ViewZoomed
handler 함수에서 사용 가능한 인수
sheet: 이벤트를 트리거한 시트
sheetName: 시트의 이름
newZoomFactor: 새로운 확대/축소 배율, 사용자는 실제 확대/축소 액션을 간섭하기 위해 약간의 변경을 할 수 있습니다.
oldZoomFactor: 이전 확대축소 배율
