I am creating a simple add-on in Blender. Initially I tested the code in Python console, then I wrapped it in an operator and added it to Object menu, it worked well:



class MyOperator(bpy.types.Operator):
bl_idname = 'object.MyOperator'
bl_label = 'MyOperator'
bl_options = {'REGISTER', 'UNDO'}

def execute(self, context):
# ...affairs...
return {'FINISHED'}


def task_func(self, context):
self.layout.operator(MyOperator.bl_idname)


def register():
bpy.utils.register_class(MyOperator)
bpy.types.VIEW3D_MT_object.append(task_func)


But now I need to add several operators and a submenu. I tried this example, and but it is not working:



class MyMenu(bpy.types.Menu):
bl_idname = 'object.MyMenu'
bl_label = 'MyMenu'

def draw(self, context):
layout = self.layout
layout.operator(MyMenu.bl_idname, text=MyMenu.bl_label)


def menu_func(self, context):
# None of these is working :(
self.layout.call_menu(name=MyMenu.bl_idname)
self.layout.menu(MyMenu.bl_idname)


def register():
bpy.utils.register_class(MyOperator)
bpy.types.VIEW3D_MT_object.append(menu_func)


So, what's the problem about? How can I solve it?
