Python Maya中的浮动UI，并单击“连接”按钮，但事件不起作用

在我的例子中，我尝试在Maya中浮动QMainWindow。 在该窗口中，有三个按钮，我将事件连接到我的函数

之后，我浮动窗口并尝试单击，但它不起作用。我想知道它不工作的原因，以及如何修复它

以下是我的脚本：

谢谢

开始脚本 cfx_发动机等级 主视图类 窗口图像

如果将连接放入_init__，它将正常工作：

def __init__(self):

    # check to see if the UI exists, if so delete it
    if cmds.window(self._object_name, exists=True):
        cmds.deleteUI(self._object_name, wnd=True)

    self._parent_window = maya_main_window()
    self._main_parent_window = QtGui.QMainWindow(self._parent_window)

    self._ui = Ui_MainWindow()
    self._ui.setupUi(self._main_parent_window, self._object_name)

    self._ui.cloth_cache_bake_btn.clicked.connect(self.bake_ncache)

请注意，它仍然会从setLink触发上一次连接并更改文本。我不知道为什么，我总是在初始化中写连接函数__
