From 8c1d114dcfcc8b3d47505e3139151eec43ebbdc4 Mon Sep 17 00:00:00 2001 From: Dominik Riebeling Date: Fri, 25 Mar 2011 22:16:12 +0000 Subject: Rockbox Utility: Replace OSDaB Zip with QuaZip. This change fixes problems with zip files created with newer zip utilities (a known issue is the iLike theme). QuaZip also allows better feedback during operations without changing the imported code. Additionally Rockbox Utility and the Theme Editor are now both using QuaZip; currently Rockbox Utility uses a copy of the sources, merging them later is planned. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29645 a1c6a512-1295-4272-9138-f99709370657 --- rbutil/rbutilqt/quazip/quazip.cpp | 285 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 285 insertions(+) create mode 100644 rbutil/rbutilqt/quazip/quazip.cpp (limited to 'rbutil/rbutilqt/quazip/quazip.cpp') diff --git a/rbutil/rbutilqt/quazip/quazip.cpp b/rbutil/rbutilqt/quazip/quazip.cpp new file mode 100644 index 0000000000..3f7314a433 --- /dev/null +++ b/rbutil/rbutilqt/quazip/quazip.cpp @@ -0,0 +1,285 @@ +/* +-- A kind of "standard" GPL license statement -- +QuaZIP - a Qt/C++ wrapper for the ZIP/UNZIP package +Copyright (C) 2005-2007 Sergey A.
