이것은 쉬워야하는 것처럼 보이지만 클래스 (팝업에서 호출 됨)의 버튼 열을 업데이트하기 위해 일주일 동안 노력하고 있습니다.Kivy : 클래스의 위젯을 바깥에서 업데이트 하시겠습니까?
아래 코드를 실행하는 경우 맨 위 버튼 , 선택 팝업에서 "완료", 상단 버튼이 제거되지 않습니다 함수가 호출됩니다하지만
문제점 :
내가, 내가 할 수있는 클래스 JobDialog에서 클래스 MyWidget에 기능 refreshList 호출 할 때마다 함수가 실행 중인지 확인하십시오. 그러나 새 인스턴스가 열리고 그것이 무엇을 지는지 알 수 없다! 이것은 간단해야합니다. 나는 스파게티를 더 써서 어디에도 가지 않고있다!
입력 사항이 있습니까? APP 클래스에서 무언가를 정의해야합니까?
