PyQT 串口改动每次点开时更新串口信息

class MainWindow(QWidget, Ui_Form):def __init__(self):super().__init__(parent=None)self.setupUi(self)self.comboBox.installEventFilter(self)	# 加载事件过滤器self.comboBox.addItems(get_ports())def eventFilter(self, obj, event):	# 定义事件过滤器if isinstance(obj, QComboBox) and event.type() == QEvent.MouseButtonPress:	# 判定是否是对应的事件obj.clear()obj.addItems(get_ports())return super().eventFilter(obj, event)

当每次点击时候，就会自动更新串口数据
