나는 영역의지도를 보여주는 응용 프로그램을 만들고 있는데, 정보를 나타낼 수있는 노드를 그리는 중입니다.PyQt - 위젯을 위젯으로 표시합니다.
나는 모든 것을 만들었지 만, 내가 보여준 하나의 맞춤 위젯을 만들고 매회 모든 정보를 변경하면서 모든 것을 계속해서 인쇄했다. 또한 원래 위젯의 이미지이기 때문에 노드를 리스너에 '연결할 수 없습니다'.
이렇게하면 GUI를 수정하고 모든 클래스를 맞춤 위젯으로 만들려고합니다! 하지만 문제가 있습니다. 내지도 노드가 더 이상 표시되지 않습니다.
는 I에 유래를 검색하고이 도움이 스레드 발견 (?) How to set absolute position of the widgets in qt
그래서 내 mapnodes 부모, 부모 = 표시되는 위젯 어쨌든
