Hello,

I'm trying to creat nodes with images, but it can't display the images. Could someone tell me how to do with this ? Thanks a lot.

Hi Mingyi,

Apologies for the late reply. This example might help: http://eclipse.org/gmt/epsilon/examples/index.php?example=org.eclipse.epsilon.eugenia.examples.friends

Cheers,

Hi all,
I have followed the instructions onhttp://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-nodes-with-images/ and I have gone as far as running the editor again with this custom figure code. For that, I had to do some additional work on the manifest file of the Eugenia project (http://screencast.com/t/u6jbe3W9Cln3) and also I have introduced a dependency from the *.diagram project to the Eugenia project. Finally, I have included the images directory in the *.diagram project and I have included that images folder in the build configurations (bin and src) in the plugin.xml of that project (http://screencast.com/t/RC5mtpoPCG9). These steps are based on some non-Epsilon-specific google searches and my personal intuition so please let me know if I have done something too much or too little (I am not an Eclipse plugin expert).

I am currently facing the problem of a NPE when using the Eugenia based editor. More specifically, the essential line with the imageDescriptorFromPlugin call returns null. Therefore, it seems that still I am missing something in my build configuration. I would be very grateful when learning how to fix this. Perhaps http://www.eclipse.org/gmt/epsilon/doc/articles/eugenia-nodes-with-images/ can be extended with some build/deploy instructions or pointers for Eclipse plugin dummies?

Thanks in advance for your insights,
Pieter

Hi Pieter,

I guess it would be easier to figure out what's going wrong by comparing your implementation against the complete implementation provided here http://eclipse.org/gmt/epsilon/examples/index.php?example=org.eclipse.epsilon.eugenia.examples.friends

If the problem persists, please send us your zipped project at epsilon.devs gmail com and we'll be more than happy to help.

Cheers,
Dimitris
