836 \brief the QZipReader class provides a way to inspect the contents of a zip -
837 archive and extract individual files from it. -
838 -
839 QZipReader can be used to read a zip archive either from a file or from any -
840 device. An in-memory QBuffer for instance. The reader can be used to read -
841 which files are in the archive using fileInfoList() and entryInfoAt() but -
842 also to extract individual files using fileData() or even to extract all -
843 files in the archive using extractAll() -
