# Qt可以獲取系統中的標准用戶變量：
# 添加頭文件
#include <QStandardPaths>

# 示例： 獲取桌面文件夾路徑

QString desktop_path = QStandardPaths::writableLocation(QStandardPaths::DesktopLocation);


＃ 以下為各變量：

        ConfigLocation,
        DownloadLocation,
        GenericCacheLocation,
        GenericConfigLocation,
        AppDataLocation,
        AppConfigLocation,
        AppLocalDataLocation = DataLocation
