[兼容性问题] 在python3.10及以上版本 dataclass 的处理方式问题

[wang-zhuo996]

在python 3.10及以上版本，直接使用QColor 会导致出现ValueError 运行失败

请提供报错信息

button.py 文件还有几处使用dataclass装饰器的类有类似错误
SwitchStyleData RadioButtonStyleData
还有一个存在于 文件 slider_.py 的 类 CoordinatePickerStyleData 里

可是我的也是3.10版本，但是正常运行

后续应该彻底避免直接构造 QColor 而是使用元数据

[ChaXxl]

Python 3.12 同样的报错

[ChaXxl]

将所有在 dataclass 里面涉及 QColor 的代码改成这样就行了：

from dataclasses import dataclass, field

...

class RadioButtonStyleData(QObject):

    STYLE_TYPES = ["Button"]

    # text_color = QColor("#D1CBD4")
    # description_color = QColor("#918497")

    # 替换为 default_factory
    text_color: QColor = field(default_factory=lambda: QColor("#D1CBD4"))
    description_color: QColor = field(default_factory=lambda: QColor("#918497"))

...
