本文记录如何使用 Qt 加载外部字体文件，并遍历字体名称和样式名称。

bool LoadFont(const QString& fontPath) {
    const int fontId = QFontDatabase::addApplicationFont(fontPath);
    if (fontId == -1) {
        return false;
    }

    // 遍历字体名和样式名
#if QT_VERSION >= QT_VERSION_CHECK(6, 0, 0)
    const QStringList fontFamilyList = fontDb.applicationFontFamilies(fontId);

    QString fontFamily;
    foreach (fontFamily, fontFamilyList) {
        qDebug() << "Family:" << fontFamily;

        const QStringList fontStyleList = QFontDatabase::styles(fontFamily);
        QString fontStyle;
        foreach (fontStyle, fontStyleList) {
            qDebug() << "\tStyle:" << fontStyle;
        }
    }
#else
    QFontDatabase fontDb;
    const QStringList fontFamilyList = fontDb.applicationFontFamilies(fontId);

    QString fontFamily;
    foreach (fontFamily, fontFamilyList) {
        qDebug() << "Family:" << fontFamily;

        const QStringList fontStyleList = fontDb.styles(fontFamily);
        QString fontStyle;
        foreach (fontStyle, fontStyleList) {
            qDebug() << "\tStyle:" << fontStyle;
        }
    }
#endif

    return true;
}
