Unsolved QPyDesignerCustomWidgetPlugin trouble with propertyEditor

[dzukenukem]

Hi! I try to realize self plugin fot QtDesigner and gain control over dynamic properties in GUI via QPyDesignerCustomWidgetPlugin. But in the initialize function, the propertyEditor () method returns None. What am I doing wrong?
Thank you in advance.

Здравствуйте! Я пытаюсь реализовать плагин для QtDesigner и управлять динамическими свойствами через GUI с помощью QPyDesignerCustomWidgetPlugin. Но в функции initialize метод propertyEditor() возвращает None. Что я делаю не так? Заранее спасибо.

class VBWidgetPlugin(QtDesigner.QPyDesignerCustomWidgetPlugin):

    create_property = QtCore.pyqtSignal(QtCore.QObject)

    def __init__(self, parent=None):
        super(VBWidgetPlugin, self).__init__(parent)
        self.initialized = False
        self.factory = None
        self.manager = None
        self.button = None
        self.property_manager = None
        self.create_property.connect(self.identify)

    def initialize(self, formEditor):
        if self.initialized:
            return
            
        self.property_manager = formEditor.propertyEditor()
        if self.manager:
            self.factory = VBWidgetExtensionFactory(self.manager)
            self.manager.registerExtensions(self.factory, Q_TYPEID['QPyDesignerPropertySheetExtension'])
        self.initialized = True

    def isInitialized(self):
        return self.initialized

    def createWidget(self, parent):
        self.widget = VBWidget(parent)
        self.widget.installEventFilter(self)
        return self.widget

You need to provide a MRE (Minimal Reproducible Example). What you have provided cannot be copy/pasted and ran which means anyone trying to figure out your issue is going to have to create code of their own which may not match what you are doing thus they may not get the issue you are having. Do yourself a favor and provide an MRE so that someone can answer your question quicker and more accurately
