KGraphViewer is a Graphviz dot graph file viewer for KDE. It is part of the KDE extragear graphics package.

Release of version 2.1.1. This is a bugfix only release that makes the kgraphviewer library cleaner: all necessary headers are installed and no more and with a proper d-pointer in its sole exported class. There is also a little bugfix in the background color setting dialog.

Previous version (2.1) included one new visible feature (option to set the default background color) and a bunch of bug regression corrections (thanks to new contributors) and, more importantly, new integration possibilities as the viewer can now be integrated in an application either as a plugin (KPart) or as a real widget. Note that from now on, the kgraphviewer code is hosted on the KDE git repository instead of svn.

Last but not least, Milian Wolf has setup kgraphviewer to be built on OpenSuse build service, thus giving a bunch of new binary packages for various distributions (see links below).

The editor works but is still very young. It demonstrates the use of the KGraphViewer part (KDE plugins) as a changeable view of a graph.

KGraphViewer is now included in several GNU/Linux distributions !

The tool works very well for most dot graphs. Here are some of its currently implemented features:
- zooming
- threaded 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;
- 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 existing window (configurable)
- help system
- internationalization
- background color selection
- ...

Kgraphviewer is using the boost/spirit library for graphs parsing.

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 http://bugs.kde.org
and not as comments here. Thanks.

Hi there,

have not compiled it yet, but looks rather interesting. One note sofar: your INSTALL still refers to configure/make instead of SCONS.

 Error compiling

I am using KDE 3.4.1, SlackWare 10.1 (Vector Linux) and it does not compiles. It finishes with this messages:

scons: Building targets ...

Regarding the Slack package mentioned above, it installs fine but crashes when reading a dot file from the graphviz 2.2.1 distribution.

Concerning compilation: it seems that your Qt is compiled without STL support. KGraphViewer will compile only with a STL-enabled Qt. Sorry. You'll have to find the right Qt package or compile it yourself...

Slacky package: the 0.9 version had a bug when used with GraphViz 2.8. Maybe do you have i ? This problem is solved with 1.0rc1

All texts are disappeared.

I use this program for dot file in KDE session of Ubuntu 7.04.

Any suggestion, please?

What version of graphviz (dot -V) do you have ? I just saw this same bug with graphviz 2.12 under Mandriva 2007.1.
I'll correct that as soon as possible

I just corrected the problem, at least for me. I'll do a bug fix release in 2 weeks after giving time to the i18n team to continue the translation.
If, in the meantime, you want to try the fix, you can download the source from the KDE extragear SVN.
I'll put a note here when the new version will be available.

Try the new 1.0.4. It should solve the problem.

Newer veersions of kgraphviewer does not compile in ubuntu feisty (AMD64). For v. 1.0.3 I got:

../../../src/src/part/dotgrammar.h:25:37: error: boost/throw_exception.hpp: No such file or directory
../../../src/src/part/dotgrammar.h:26:33: error: boost/spirit/core.hpp: No such file or directory
../../../src/src/part/dotgrammar.h:27:45: error: boost/spirit/utility/distinct.hpp: No such file or directory
../../../src/src/part/dotgrammar.h:28:42: error: boost/spirit/utility/loops.hpp: No such file or directory

Version 1.0.4 does not compile at all. I guess it is related to the following warning:

Makefile:965: warning: overriding commands for target `clean-bcheck' > Makefile:928: warning: ignoring old commands for target `clean-bcheck'

Version 1.0.2 (and earlier) compiles but then some elements of the graph are completly black and then unreadable. It is probaly related to runtime warnings:

kgraphviewer: WARNING: xdot render operation 'c' is currently not supported (ignored).
Usually its value is handled through standard attributes
QColor::setHsv: HSV parameters out of range

For all versions, you need the boost libraries (devel package) installed. It should be tested by the configure script.

For the 1.0.4, that you should use, it seems that it is the checking code that causes problems. A full output of the messages would be helpful. Even better, a bug report at bugs.kde.org would help to solve the problem.

Older versions are not supposed to work anymore.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
