deepin pr auto review

关键摘要:

• 在QtObject中添加了对WindowManagerHelper的依赖，需要确认是否所有使用该对象的代码都已更新以处理新的条件逻辑。
• 修改了InsideBoxBorder的radius属性，使用了WindowManagerHelper来判断是否启用圆角，这是一个好的做法，但需要确保相关文档和测试用例都已更新以反映这一变化。

是否建议立即修改:

• 是，建议立即更新相关文档和测试用例，以确保代码的完整性和正确性。同时，需要检查是否有其他代码依赖于WindowManagerHelper，并确保它们也得到了相应的更新和测试。
