QTableView의 rigth-click에서 행 번호를 얻는 방법은 무엇입니까?

Question

PyQt5로 앱을 개발 중이며 QTableView에서 오른쪽 클릭의 위치를 ​​행 번호로 변환하는 방법을 찾을 수 없습니다. 구현 한 방법은 QPoint 커서 위치에서 rowAt 메서드를 사용하는 것으로, 클릭 한 실제 행 번호와 오프셋이있는 것처럼 보이는 행 번호가 표시됩니다. 나는 주변을 둘러 보았지만 명확한 해결책을 찾지 못했습니다. 스크롤 영역과 관련이있는 것 같습니다. 내 코드 예제는 다음과 같습니다. Qt는 디자이너 생성

하는 UI 코드 :

Answer 1

rowAt있어서, 로컬 좌표를 사용한다. 그래서 올바른 Y 값을 얻을 수 mapFromGlobal를 사용해야합니다 반환 된 행이 입니다

class Gui(QMainWindow, Ui_MainWindow): 
    ... 
    def contextMenuEvent(self, event): 
     ... 
     pos = event.globalPos() 
     removeAction.triggered.connect(
      lambda: self.remove_row_from_rigth_click(pos)) 
     self.menu.popup(pos) 

    def remove_row_from_rigth_click(self, q_point): 
     row = self.tableView.rowAt(
      self.tableView.viewport().mapFromGlobal(q_point).y()) 
     print("row =" + str(row))
