Having spent today immersed in pypy's dotviewer's internals I can tell that it doesn't use 'xdot' as the intermediate format; it uses the simplest and most crippled 'plain' format, and that causes problems.

This is so cool! I have experimentally compiled Graphviz for the Maemo operating system, put it on my Nokia N800, and then used 'xDot' to successfully navigate around some sample 'dot' files with it! To enable the use of the device's zoom buttons, I added some F7 and F8 'keysymbs'. Does xDot use the GPL license?

darethehair,

XDot uses the LGPL license, which means you can use it in closed source projects as long as the xdot module itself is kept open source. Of course, it is difficult to conceive closed source python software unless one goes out of its way and uses byte code, or code obfuscators, etc.

I do like this tool. Well done! I'm actually using this inside a wxPython application of all places, as this seems to be a nice alternative to the wx floatcanvas package.

The only comment I have is that shapefile nodes aren't supported, as XDotAttrParser::parse writes "unknown xdot opcode 'I' " when it encounters the draw field . If I had the time to dig around the internals (alas there are only 24 in the day) I would have a shot at trying to implement this myself. In the meantime, if you are looking for more xdot features to implement, you could do a lot worse than add shapefile support :-)

Really good !!!

I now can see my UML that I create parsing PHP files easier than before. Now you only have to implement an editor on the left :)

I downloaded version 0.4 from SVN. But the sample.py have not worked for me earlier. I changed two rows in 3 places (filled=True; handle_ellipse; EllipseShape?), and now it works well. (Upper rows are the good rows.)

$ diff xdot.py xdot2.py 
625c625
<     def handle_ellipse(self, x0, y0, w, h, filled=True):
---
>     def handle_ecllipse(self, x0, y0, w, h):
629c629
<         self.shapes.append(EllipseShape(self.pen, x0, y0, w, h))
---
>         self.shapes.append(EclipseShape(self.pen, x0, y0, w, h))

I like it.

Thanks arpad. I really need to make a testsuite to catch this kind of problems earlier on.

Please provide some more samples.

How do I add a node? Does it have to re-process all the code i want to add a node? Can I remove a node?

eldmannen,

Xdot.py is just a viewer for graphviz's dot language. It does not support editing. To change the graph you'll need to regenerate another dot file.

See http://www.graphviz.org/Documentation.php for the dot languange documentation and examples; and see http://code.google.com/p/yapgvb/ , http://software.inl.fr/trac/wiki/GvGen , and http://code.google.com/p/pydot/ for python libraries that can help generate those graphs in the dot language.

Hey very cool and fairly lightweight (no JAVA yaaay \o/ :D) dot viewer. I've made a tiny patch that reloads the file on the 'r' key and I find it quite useful :) It would be even nicer if it was able to watch the file for changes automatically. Maybe I'll add that later.

Great tool, very light weight. I hacked in a "Find" button to search through node text. I've never used gtk or python before so its probably a little rough, but it does work. Any where I can send code back to contribute?

butterfoss,

Please open an issue and attached a patch or the modified source code.

Simplemente, es perfecto. Justo lo que andaba buscando.
