Javafx에서 스크롤 창의 내용을 변환하는 방법은 무엇입니까?

Question

안녕하세요 저는 현재 특정 사용자 상호 작용에 따라 스크롤 창 콘텐츠의보기를 이동하는 중입니다. 응용 프로그램에서 동일한 크기의 화면과 동일한 크기의 3 개의 이미지 뷰가 포함 된 gridPane이 있습니다. 확대/축소와 패닝에 관련된 모든 함수는 괜찮습니다. 그러나 scrollpane (또는 그 내용을 시도했습니다)을 setTranslateX()를 통해 변환하려고 시도하고 매개 변수를 화면 폭으로 설정하면 스크롤 구획의 경우는 내용이 표시됩니다. 아래 코드는 "WorldProvincialMap-v1.01.png"에 대한 이미지를 대체하면 동일하게 작동합니다. 코드는 원하는 결과를 얻지 못하는 오류를 생성하지 않습니다.

Answer 1

나는 mapScroll.setHvalue()를 사용해야하는 내용을 번역하기 위해; 매개 변수로 두 배가됩니다 (픽셀 이동이 아님).
