Description:
 Release of version 1.0

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.

of Apply button
  * make appear the bird-eye view even if it was
not initialy appearent when
    zooming
  * optimizations to be able to load and

    graph OK)

2006/05/23
  * documentation

2006/05/18
  * corrected placing of window position indicator
(red line) in bird eye view 
    when zooming
  * add tooltips and whatsthese everywhere
  * corrected tooltips placement

2006/05/17
  * corrected drawing errors appearing when
dragging after a zoom by updating
    Qt to 3.3.6

2006/05/16

  * correct handling of record shaped nodes (see
graphviz examples, compare with doted results)
  * corrected handling of fonts (see graphviz
examples, compare with doted results)
  * corrected drawing of some undirected graphs in
graphviz examples (compare with doted results)
  * added support for main graph label

2006/05/14
  * corrected drawing of clusters (compared with
doted results)
  * hack to not freeze with huge graphs. Stop
loading after N vertices or edges (N currently set
to 1000)

2006/05/13
  * make the window position indicator to be still

    lot (min size or big bold point)

2006/05/12
  * added hard-coded min and max zoom factors
  * scrolling with mouse wheel

2006/04/11
  * Added support for a new dot attribute:
shapefile, allowing to define nodes content by an

one page (beginning of a better printing support)

2006/04/08
  * session management (reload of previously
opened files)
  * context menu to use other layouting algorithms
(twopi, fdp, etc.)
