스톱워치 응용 프로그램을 만들었는데 테스트했을 때 일시 중지 버튼을 누른 후 중지 시계가 0으로 재설정되는 문제가 있음을 알게되었습니다. (사용자가 버튼을 일시 중지 한 후 시작 버튼을 누르면 스톱워치가 0에서 시작됩니다). 다음은 내 코드입니다 :일시 중지 버튼을 누른 후 스톱 워치가 0으로 재설정됩니다. 내 코드에서 잘못되었을 수 있습니다.

어떤 도움을?!
EDIT 1 : 방금 변수 "zero pause"를 추가하고 사용자가 버튼 시작과 일시 정지 버튼을 누른 순간부터 시간 차이를 계산하여 문제를 해결했습니다.
아무도 알아낼 수없는 부분이 있습니까? –
