# You may declare properties like following, framework will automatically add and remove them.
# Do not define your own property group class in the __init__.py file. Define it in a separate file and import it here.
# 注意不要在__init__.py文件中自定义PropertyGroup类。请在单独的文件中定义它们并在此处导入。

# Best practice: Please do not define Blender classes in the __init__.py file.
# Define them in separate files and import them here. This is because the __init__.py file would be copied during
# addon packaging, and defining Blender classes in the __init__.py file may cause unexpected problems.
# 建议不要在__init__.py文件中定义Blender相关的类。请在单独的文件中定义它们并在此处导入它们。
# __init__.py文件在代码打包时会被复制，在__init__.py文件中定义Blender相关的类可能会导致意外的问题。
