Pyqt에서 동적으로 생성 된 QComboboxes에 항목을 추가하는 방법

Question

동적으로 생성 된 콤보 상자에 항목을 추가하려고합니다. 변수가 스스로 재정의하고 원하는 결과를 얻을 수 없다는 것을 알고 있습니다. 콤보 박스 (Combobox) 액션은 원하지 않는 마지막 항목에 항목을 추가합니다. 다음 항목을 오른쪽에 추가해야합니다.

if __name__ == "__main__": 
    import sys 
    app = QtGui.QApplication(sys.argv) 
    MainWindow = QtGui.QMainWindow() 
    ui = Ui_MainWindow() 
    ui.setupUi(MainWindow) 
    MainWindow.show() 
    sys.exit(app.exec_()) 

여기 내가 약간의 변경이 필요하다고 생각합니다. 나는 objectnames 설정을 시도하고 어떻게 든 comboboxes를 연결하지만 나는하지 않았다.

def addItem(self, activetext): 
    # sendin = self.centralwidget.sender() 
    self.scomboBox.addItem(activetext) 

Answer 1

나는이 문제를 해결한다. ObjectName과 findChild의 사용을 발견하고 몇 가지 변경을했습니다.

여기가 해결책입니다.

def addItem(self, text): 
    sendin = self.centralwidget.sender() 
    objname = str(sendin.objectName()) 
    objnamevalue = objname.split('_')[1] 
    self.centralwidget.findChild(QtGui.QComboBox, 'ScomboBox_' + objnamevalue).addItem(text)
