一，使用QFontDatabase::addApplicationFont() 函数加载所有的字体文件，设置fontFamily即可。


void loadFontFimily()
{
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");
    QFontDatabase::addApplicationFont(QApplication::applicationDirPath() + "/asset/font/*.otf");

    QString sanFamily = "XXXXXXXX 2.0";
    QFont defaultFont(sanFamily);
    QApplication::setFont(defaultFont);
}
