Description:
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.
