drop_file_event
을 원하시는 분 mpl_connect
에 의해 처리되었습니다. 불행히도 이것은 documentation에 따른 사례는 아닙니다 (어쨌든 일반 플로팅 라이브러리의 경우 약간의 경우입니다).
그러나 GUI 처리 드롭 이벤트를 구현하는 것은 그렇게 어렵지 않습니다. 다음은 대부분 embedding_in_wx2을 기반으로하고 wx.FileDropTarget
을 추가 한 예입니다.

나는 뭔가를 놓치지 않았 음을 알아두면 좋을 것 같습니다. GUI에 대한 나의 모험은 내가 계획했던 것보다 일찍 시작된다. 예를 들어 주셔서 감사합니다. – user3744040
