关于fluentwidgets亮暗模式切换的问题

from PySide6 import QtWidgets
from ui.UIstatistics import Ui_Form_statistics
from qfluentwidgets import ScrollArea,isDarkTheme
from config import cfg

class statisticsPage(ScrollArea,Ui_Form_statistics):
    def __init__(self):  
        super().__init__()  
        self.setupUi(self)
        self.__setQss()
        cfg.themeChanged.connect(self.__setQss)

    def __setQss(self):
        """ set style sheet """
        self.scrollArea.setObjectName('scrollArea_statistics')

        theme = 'dark' if isDarkTheme() else 'light'
        with open(f'resource/qss/{theme}/statistic.qss', encoding='utf-8') as f:
            self.setStyleSheet(f.read())

/* statistic.qss */
statisticsPage, #scrollAreaWidgetContents {
    background-color: rgb(39, 39, 39);
}

QScrollArea {
    border: none;
    background-color: rgb(39, 39, 39);
}

/* 标签 */
QLabel#settingLabel {
    font: 33px 'Microsoft YaHei Light';
    background-color: transparent;
    color: white;
}

需要注意__setQss函数以及qss文件的编写，objectName的名称要唯一。
