PyQt5-如何操作QObject对象的信号相关函数

1、信号可以通过connect(slot)函数与槽连接。以QObject的两个信号destroyed,objectNameChanged为例：信号：destroyed(p_object=None)对象被销毁时发射此信号：self.obj1 = QObject(）def objDes(): print('对象被释放了')self.obj1.destroyed.connect(objDes)del self.obj1

3、信号：objectNameChanged(p_str)监听某个对象名字发生改变发出信号。self.obj1 = QObject()def objPrint(): print('名字改变了')self.obj1.objectNameChanged.connect(objPrint)self.obj1.setObjectName('NEW-NAME')
