How to share variable between def in class? [duplicate]
You can set it as self.board. Like this:
class MainWindow(QtWidgets.QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
def buttonClicked5(self):
self.board = Arduino(self.ui.comboBox.currentText())
communication_start = "Communication Successfully started"
self.ui.lineEdit_4.setText(communication_start)
def closeEvent(self, event):
self.board.exit()
