EMFForms: selecting different viewmodels programatically [message #1816115]

Currently I use the method ECPSWTViewRenderer.INSTANCE.render(parent, eObject) to embed the EMFForm - based GUI into the application. This method invokation works well if there is only one viewmodel registered for a certain EObject.

Now I have several viewmodels registered to the same EObject to be able to render the GUI differently.

I saw that there are several overloaded versions of the ECPSWTViewRenderer.INSTANCE.render method, but I do not know how to parameterize that one correctly with the right viewmodel.

Thank you for your help in advance!

HI Tamas,

in order to provide the view model using the ECPSWTViewRenderer.INSTANCE.render method you need this call:

final VView view = ViewProviderHelper.getView(domainObject, null);
			final ViewModelContext viewModelContext = ViewModelContextFactory.INSTANCE.createViewModelContext(view, domainObject);
			ECPSWTViewRenderer.INSTANCE.render(content, viewModelContext);

You can use this only if you have the rendering step under control.

If you want to select the view model dynamically, you can provide a custom View Provider as an OSGi Service:
just extend

org.eclipse.emf.ecp.view.spi.provider.IViewProvider

org.eclipse.emf.ecp.view.spi.provider.IFilteredViewProvider

Best,
Eugen
