[ECP] Custom E4 Application [message #1709735]

Hello everybody,
I recently started exploring the EMF/ECP technologies and walked through the good introductions and tutorials on eclipsesource and vogella. Now I want to build my own custom application without using the tutorials and example projects, but encountered problems.

Working with Eclipse Mars 4.5, I created an E4 application and added an ECPModelView as well as an ECPRepositoryView as part to the application model. Further I created a simple EMF model and generated the code. Now I want to create arbitrary model instances within projects with help of the Model Explorer (ECPModelView).

Unfortunately, I couldn't figure out, how to use the EMF model as a basis for the ECPModelView. Is there something like a global model context for ECP views, where I can programmatically deposit my model?

It would be great, if someone could give me a hint on this!
Thanks in advance,
Michael

Hi Michael,
so you want to reuse the ECPModelView as well as the ECPRepositoryView in your custom e4 application?
You should be able to right click in the modelview and create a new project. In there you should be able to add new model elements by again right clicking and selecting "New Model Element" .
You can find the ecp e4 application here:
http://git.eclipse.org/c/emfclient/org.eclipse.emf.ecp.core.git/tree/bundles/org.eclipse.emf.ecp.application.e4
and the implementation of all views here:
http://git.eclipse.org/c/emfclient/org.eclipse.emf.ecp.core.git/tree/bundles/org.eclipse.emf.ecp.ui.e4

Cheers,
Eugen

As you create your own e4 model, you will have to add at least two commands with the following handler classes:
org.eclipse.emf.ecp.ui.e4/org.eclipse.emf.ecp.ui.e4.handlers.NewProjectHandler
and
org.eclipse.emf.ecp.ui.e4/org.eclipse.emf.ecp.ui.e4.handlers.NewModelElementHandler

Don't forget to add handledMenuItems/HandledTooltems to use those handlers.

Cheers

Hi Eugen,
thanks for your help, your inputs were exactly what I needed!
I added the context menu items to the explorer one by one and my E4 ECP application is running smoothly now...
The fact that the menus were missing confused me a bit and made me think, that there is something wrong with my model plug-in deployment.
So thanks a lot again, and greetings!
