Description:
 KGraphViewer is now part of the KDE extragear
graphics package. The 1.0.4 has no new technical
feature but corrects a few bugs and thanks to the
work of the marvellous KDE's i18n team, it is now
available in 26 languages! : da el en fr it ka pt

A previous version (1.0.2) is now part of the
Mandriva 2007 distribution !

KDE4 Version: first (partly) working preview.
Works with kdelibs trunk revision 561764. Uses the
new QGraphicsView ! Look at the third screenshot.
It is now very outdated !

Note: KDE 4 is usable but not ready at all. This
snapshot is just for preview by "power users".
Enjoy !


KGraphViewer is a Graphviz dot graph file viewer
for KDE.

I used, in this program, code from the profiling
tool kcachegrind and from koffice/kexi.
 (http://kcachegrind.sourceforge.net/cgi-bin/show.cgi/KcacheGrindIndex).

The tool works very well for not huge graphs (<
1000 nodes).
Here are its currently implemented features:
- zooming
- loading of several graphs in tabs;
- saving of the recent files list;
- manual reload of files;
- display of a bird-eye view of the graph;
- moving of the graph by dragging;
- full featured printing;
- closing of the tabs;
- perfect drawing of all graphviz example graphs;
- automaticaly choose dot for directed graphs and
neato for undirected
- possibility to use an arbitrary layout algo as
soon as it produces xdot format
- automatic reloading with user confirmation of
(externaly)
  modified files (configurable) ;
- open new instances as new tabs in the old one
(configurable)
- help system
- internationalization (currently eng, fre)
- ...

Kgraphviewer is using the boost/spirit library for
graphs parsing. To avoid
external dependencies, these Boost parts have been
integrated in Kgraphviewer.

See TODO in the distribution for planned features.


As usual, comments, bug reports and any help are
very welcome !

Please report bugs or install problems directly on
the kgraphviewer homepage
and not as comments here. Thanks.
