Hi guys,

I was creating an ecore model to extend e4 application model. That being done, now I want to use the extension model in a fragment model so that I can create elements of my own created type.

Luckily Lars Vogel has an article for this topic. I cannot paste the link but anyone is interested can google "Extending the Eclipse 4 application model- Tutorial".
I don't know how he managed to add his "xmlns:extension="his_ecore_NS_URI" to his e4 application model.

How to achieve this with "Eclipse 4 model editor"? (I tried to add it with text editor but e4xmi file doesn't take it..) Am I missing any tools/ui plugins?

Thanks,
Johnny

The editor does not recognize your additions (it does not work
reflectively) but it provides extension points to register new
form-editors. The Simple IDE stuff provides such extensions for the editor.

Thanks Tom! The SimpleIDE is awesome, great job!

An off topic question, I am using e4 to build a desktop application that needs to have a diagram editor. Earlier this year I used Graphiti in an Eclipse Indigo RCP prototype and it turned out pretty well. Now I am trying to start Graphiti in e4 application. Apparently Graphiti requires some stuffs like org.eclipse.ui that e4 doesn't like.

I posted detailed question at eclipse graphiti forum
http://www.eclipse.org/forums/index.php/t/369969/

Do you have any suggestions or comments? Thanks again!

Hi Johnny,

if you want to know how to extend the Eclipse e4 application model, this is the same as extending any EMF model. See http://www.vogella.com/articles/EclipseEMF/article.html#inheritance for an introduction.

Best regards, Lars

Thank you Lars. Great tutorials.

I have created my own model that extends Eclipse e4 application model. What's confusing is at http://www.vogella.com/articles/Eclipse4ExtendModel/article.html#renderer_xmi

I don't know how you add "xmlns:extension="http://www.vogella.com/ui/e4/extension"" to your e4xmi file.

Best regards,
Johnny
