It can be - * used to read table contents of the ZIP archive and retreiving - * information about the files inside it. - * - * You can also use this class to open files inside archive by passing - * pointer to the instance of this class to the constructor of the - * QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*) - * for the possible pitfalls. - * - * This class is indended to provide interface to the ZIP subpackage of - * the ZIP/UNZIP package as well as to the UNZIP subpackage. But - * currently it supports only UNZIP. - * - * The use of this class is simple - just create instance using - * constructor, then set ZIP archive file name using setFile() function - * (if you did not passed the name to the constructor), then open() and - * then use different functions to work with it! Well, if you are - * paranoid, you may also wish to call close before destructing the - * instance, to check for errors on close. - * - * You may also use getUnzFile() and getZipFile() functions to get the - * ZIP archive handle and use it with ZIP/UNZIP package API directly. - * - * This class supports localized file names inside ZIP archive, but you - * have to set up proper codec with setCodec() function. By default, - * locale codec will be used, which is probably ok for UNIX systems, but - * will almost certainly fail with ZIP archives created in Windows. This - * is because Windows ZIP programs have strange habit of using DOS - * encoding for file names in ZIP archives. For example, ZIP archive - * with cyrillic names created in Windows will have file names in \c - * IBM866 encoding instead of \c WINDOWS-1251. I think that calling one - * function is not much trouble, but for true platform independency it - * would be nice to have some mechanism for file name encoding auto - * detection using locale information. Does anyone know a good way to do - * it? - **/ -class QUAZIP_EXPORT QuaZip { - friend class QuaZipPrivate; - public: - /// Useful constants. - enum Constants { - MAX_FILE_NAME_LENGTH=256 /**< Maximum file name length.
