Define a ViewerContentProvider for each TreeFormView [message #1838019]

Hello,

I'm discovering Parsley which is a very good project.
I setuped a project with RAP, and I created several entry points to display different perspectives and views.
I'm loading the same object from an xmi in a configurator defined in an EmfParsleyGuiceModule.

What I would like to to is to filter this big EObject depending the TreeFormView.
My problem is that ViewerContentProvider that I defined is defined in my EmfParsleyGuiceModule which is project wide so, I cannot make my filtering on views like I want.
Is there a solution to have a different content provider for each TreeFormView I defined ?
I'm attaching a schema of the architecture I would like to reach.

Thank you

Hi
if you need different customizations, then you need different Guice Modules.
You can have another Guice Module in the same project. If you use the DSL you can have several DSL files in the same project. When you specify something like a content provider, you can specify that it extends an existing one, in case you want to reuse something.
Is that what you meant?
cheers
Lorenzo

Hello Lorenzo,

Thanks for your fast answer. This is exactly what I want. But how to use the other Guice Module for a given SaveableTreeFormView ? Shall we inject it in the TreeFormView like the following code ? Is there another way to map the Guice Module to use and the given view ?

import com.google.inject.Inject;

public class Example1SaveableTreeFormView extends org.eclipse.emf.parsley.views.SaveableTreeFormView {
	@Inject
	private EmfParsleyGuiceModule1 module;
}
import com.google.inject.Inject;

public class Example2SaveableTreeFormView extends org.eclipse.emf.parsley.views.SaveableTreeFormView {

	@Inject
	private EmfParsleyGuiceModule2 module;
}

Thanks a lot

No, you should not inject a Guice Module: you should create an injector from a Guice Module and then create your components with that injector. (please, make sure you also read the section "Dependency Injection With Google Guice" in the documentation, https://www.eclipse.org/emf-parsley/documentation.html).
The easiest thing to do is to create a DSL file, where you also define your view; similar to the one you created with the wizard (assuming you have already started with a wizard).

I mean that by using the DSL you get for free all the infrastructure that creates an Eclipse view via injection and using all the customizations specified in that specific DSL file.

Hello, yes I was going to reply when you provided additional input.
I created several dsl *.parsley files with the different configuration needed and it works like a charm !
Thanks a lot for your help. EMF Parsley is really great !
