Closes any open archive and releases used resources.
| QString UnZip::archiveComment | ( | ) | const |
| void UnZip::closeArchive | ( | ) |
Closes the archive and releases all the used resources (like cached passwords).
| bool UnZip::contains | ( | const QString & | file | ) | const |
Returns true if the archive contains a file with the given path and name.
| QList< UnZip::ZipEntry > UnZip::entryList | ( | ) | const |
Returns information for each (correctly parsed) entry of this archive.
| UnZip::ErrorCode UnZip::extractAll | ( | const QDir & | dir, |
| ExtractionOptions | options = ExtractPaths ) |
Extracts the whole archive to a directory. Stops extraction at the first error.
| UnZip::ErrorCode UnZip::extractAll | ( | const QString & | dirname, |
| ExtractionOptions | options = ExtractPaths ) |
Extracts the whole archive to a directory.
| UnZip::ErrorCode UnZip::extractFile | ( | const QString & | filename, |
| const QDir & | dir, | ||
| ExtractionOptions | options = ExtractPaths ) |
Extracts a single file to a directory.
| UnZip::ErrorCode UnZip::extractFile | ( | const QString & | filename, |
| const QString & | dirname, | ||
| ExtractionOptions | options = ExtractPaths ) |
Extracts a single file to a directory.
| UnZip::ErrorCode UnZip::extractFile | ( | const QString & | filename, |
| QIODevice * | outDev, | ||
| ExtractionOptions | options = ExtractPaths ) |
Extracts a single file to a directory.
| UnZip::ErrorCode UnZip::extractFiles | ( | const QStringList & | filenames, |
| const QDir & | dir, | ||
| ExtractionOptions | options = ExtractPaths ) |
Extracts a list of files. Stops extraction at the first error (but continues if a file does not exist in the archive).
| UnZip::ErrorCode UnZip::extractFiles | ( | const QStringList & | filenames, |
| const QString & | dirname, | ||
| ExtractionOptions | options = ExtractPaths ) |
Extracts a list of files. Stops extraction at the first error (but continues if a file does not exist in the archive).
| QStringList UnZip::fileList | ( | ) | const |
Returns complete paths of files and directories in this archive.
| QString UnZip::formatError | ( | UnZip::ErrorCode | c | ) | const |
Returns a locale translated error string for a given error code.
| bool UnZip::isOpen | ( | ) | const |
Returns true if there is an open archive.
| UnZip::ErrorCode UnZip::openArchive | ( | const QString & | filename | ) |
Opens a zip archive and reads the files list. Closes any previously opened archive.
| UnZip::ErrorCode UnZip::openArchive | ( | QIODevice * | device | ) |
Opens a zip archive and reads the entries list. Closes any previously opened archive.
