PyQt GUI 项目在其主类之外

Question

我如何在MainApp Class之外使用像pushButton这样的GUI组件？

法典

class MainApp(QMainWindow, FORM_CLASS):
def __init__(self, parent=None):
super(MainApp, self).__init__(parent)
QMainWindow.__init__(self)
self.setupUi(self)
self.btnConnect.clicked.connect(self.connect)

Answer 1

您可以将引用传递给其他对象，如下所示：

class MainApp(QMainWindow, FORM_CLASS):
def __init__(self, parent=None):
super(MainApp, self).__init__(parent)
QMainWindow.__init__(self)
self.setupUi(self)
self.btnConnect.clicked.connect(self.connect)
class MyOtherClass(object):
def __init__(self, the_button):
self.btn = the_button
myApp = MainApp()
my_other_class = MyOtherClass(myApp.btnConnect)
