I have two windows in this PyQt5 GUI application.
I need to call a function in the first window from second window on button press event. ( I am using python 3.8.10 )
I just want to load data from excel when I press an insert button in the second window. But loadExcelData() is in the first window class.
I have tried this method :
class second(QtWidgets.QMainWindow, Ui_MainWindow2):
def __init__(self):
super().__init__()
self.setupUi(self)
self.insertDatabtn.clicked.connect(self.getAndInsert)
def getAndInsert(self):
f1 = first()
f1.loadExcelData()
