Graph visualization with Vaadin and Cytoscape

Vaadin 6 / 7 / 8 Framework UI

Hi,
First of all, congrats on the great addon. But I tried using it, and I am running into problems. Wondering if you could help. I followed your instructions, added all the addons, but when I try and run your example…eclipse cannot find the “Cytoscape” part in the line below. Maybe I am forgetting something.

“Cytoscape.createNewSession();”

Thanks

PS: I tried running your online demo, it gives an Java Heap Error.

Did you also downloaded Cytoscape (2.8.1) and copied cytoscape.jar from it into your projects /WebContent/WEB-INF/lib folder? If so, please ensure also that the jar is included into your project’s build path.

Oh noes, it was ran out of memory again (the session loader part might have same memory leak)… I restarted it now, thx for pointing out the problem!

giving a try here, but no luck so far.
VaadinGraph could not be found anywhere. Documentation is outdated i think, and sadly links to samples won’t work.
Should VaadinGraph be replaced with Cytographer class?

Hello Alberto, and sorry this long delay. I managed to have some time to update QuickStart Guide and example code. Could you, please, test wheter it works now for you also.

With best regards,

Johannes, thanks for your work. I’ll be very interested in using this when you finish it. It needs more sample code to dynamically add nodes, edges, etc. Also, the online demo app crashes with a NoClassDefFoundError, so we can’t see it in action.
Cheers,

Hello!
How to change node shape?

view.getVisualStyle().getNodeAppearanceCalculator().getDefaultAppearance().set(VisualPropertyType.NODE_SHAPE, NodeShape.ROUND_RECT);

doesn’t give effect!

Hello everyone!

I faced with following trouble: “Could not initialize class cytoscape.Cytoscape”. What could be the reason? I used the sample code.

30

Will there be a Vaadin7 adaption of the plugin?

31

Is there any chance of upgrading this addon to work with Vaadin 7?

Thanks in advance.
