The visualisation type choosen is a treemap. +Treemaps allow for showing metrics of objects in nested structures, like +sizes of files and directories on your hard disc, where the the size of +directories is defined to be the sum of the size of its children. +Each object is represented by a rectangle which area is proportional to +its metric. The metric must have the property that the sum of the +children's metric of some object is equal or smaller than the objects +metric. This holds true for the file/directory sizes in the use case of +FSView. + +It's provided both as a Konqueror KPart plugin for the mime type +inode/directory, and a standalone executable. + +This was meant as a small test application and usage tutorial for +the TreeMap widget developed within KCachegrind. As it's quite cool +and small, it is now provided as a Konqueror addon in KDE. + +For a full featured graphical 'du', see KDirStat. It's quite similar +to FSView, but allows for lot of cleanup actions. + +Happy space hunting, +Josef diff --git a/konq-plugins/fsview/fsview.cpp b/konq-plugins/fsview/fsview.cpp new file mode 100644 index 0000000..b0c82d8 --- /dev/null +++ b/konq-plugins/fsview/fsview.cpp @@ -0,0 +1,540 @@ +/* This file is part of FSView. + Copyright (C) 2002, 2003 Josef Weidendorfer <Josef.Weidendorfer@gmx.de> + + KCachegrind is free software; you can redistribute it and/or + modify it under the terms of the GNU General Public + License as published by the Free Software Foundation, version 2. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
