스크롤 위젯이 보이지 않게 함

Question

기본 런처 - 프로그램 (최근 수정 됨, Scrollbar - make the background move but not the forderground 참조)에서 스크롤바를 사용할 때 버튼이 사라집니다. 사실 그들은 여전히 ​​거기에 있으며 버튼을 클릭 할 수 있지만 이제 볼 수 있습니다. 마우스 커서가 버튼 위치로 이동 한 후이 영역을 벗어나면 버튼이 다시 나타납니다. 문제는 GUI의 업데이트라고 생각합니다. 그래서 (아마도 너무 많은) programm에서 많은 업데이트를 사용하지만 여전히 작동하지 않습니다.

Answer 1

결과를 복제 할 수 없습니다. 나는 3 개의 단추를보고, 결코 떠나지 않는다.

너무 많은 업데이트를 사용하는 것이 맞습니다. 또는 update_idletask에 대한 호출이 dimensionner에 필요하지 않아야합니다.이 함수는 이벤트의 결과로만 호출되므로 함수가 호출 될 때 UI가 이미 최신 상태 여야합니다.

또한 코드 작성자는 생각하는대로 수행하지 않는 많은 코드가 있습니다. 예를 들어 :

self.bl.grid_rowconfigure(0, weight=1, pad=100, minsize=50) 

에만 버튼 내부 을 배치 버튼의 아이들에 영향을 미칠 것입니다. 귀하의 코드는 단추 내부에 위젯을 넣지 않습니다 (매우 특이합니다). grid_rowconfigure 및 grid_columnconfigure을 호출하면 행과 열 내부에이 포함 된 위젯의 행 및 열이 아닌 위젯을 구성합니다.
