Adding 3.x ViewParts to E4XMI [message #881270]

Mon, 04 June 2012 04:56

Hi Everybody,

this is just a quick and possibly easy to answer question, unfortunately I wasn't able to find much about this.

Is there an easy and straight forward way to add 3.x ViewParts to the E4XMI application model, while using the compatibility layer (especially using the E4 Workbench Model Editor)?

Thank you very much for your help!

You could try (but I never tried this myself) and take a look how the
XMI-Elements produced by the compat layer look like when a view is
opened through it.

An important fact is that e3 views are stored in the shared elements of
your window and then then linked into a perspective using Placeholders!

Hi Thomas,

thanks for your help. That indeed did the trick.

I just created a new shared element, using "bundleclass://org.eclipse.ui.workbench/org.eclipse.ui.internal.e4.compatibility.CompatibilityView" as class URI while referencing the unique ID of the 3.x ViewParts class. I then used that shared element as reference for a placeholder which I put in place of the original part and everything works as expected.

Again, thank you very much for your quick reply. I really appreciate it.

Cheers Philipp.

Hi Philipp and Thomas !

I am writing an E4 RCP application in which I want to add regular Eclipse views such as Console and Error Log. I did the following in the Application.e4xmi file:

1 - Add a PartDescriptor to the Part Descriptors section with:

Id = org.eclipse.ui.console.ConsoleView
Label = Console
Class URI = bundleclass://org.eclipse.ui.workbench/org.eclipse.ui.internal.e4.compatibility.CompatibilityView

2 - Add a Part to the Shared Elements section with the same parameters as above.

3 - Add a Placeholder in the Perspective section with:

Id = org.eclipse.ui.console.ConsoleView
Reference = Part - Console

Things seem to be declared like they appear in the model editor of Juno itself.
But, when I launch my application, I get the following error messages:

!ENTRY org.eclipse.e4.ui.workbench 4 0 2012-10-04 08:10:01.167
!MESSAGE Unable to create class 'org.eclipse.ui.internal.e4.compatibility.CompatibilityView' from bundle '229'
!STACK 0
org.eclipse.e4.core.di.InjectionException: Could not find satisfiable constructor in org.eclipse.ui.internal.e4.compatibility.CompatibilityView
	at org.eclipse.e4.core.internal.di.InjectorImpl.internalMake(InjectorImpl.java:327)

Can you help me to fix this, please ?

Hi Georges,

I do have the same problem. I started by using the wizard to create a simple E4-Application example. I then tried to add an old Eclipse3 view to. Im failing with the same error messages you got. Do you have any solution to that issue?

Cheers

Allright.... I found some answer by myself. Instead of creating an E4 RCP Application using an E3 RCP APplication it works. I just defined the E3 App to use the e4xmi model. Still I am not sure about the implications doing it this way :-/

Quick questions, has anyone tried this using a fragment?

I'm trying to contribute a perspective as fragment to the 'org.eclipse.e4.legacy.ide.application'. I do get the empty perspective to show up. I also do get to add parts to it. However, I'm sort of stuck adding placeholders for things like the editor area and existing views. It doesn't even work for views contributed as e4 fragment as well. The trouble seems to be the references. The fragment model does not have any visibility to shared elements. Thus, I'm unable to select any reference in the e4 model editor.

Does anyone have any tips how to add the editor area and other views to such a contributed perspective? Is placeholders the right approach or should I add parts and area directly?

Do you know this: https://dirksmetric.wordpress.com/2012/08/01/tutorial-eclipse-rcp-e4-with-3-x-views-like-project-explorer-properties-etc/

Are you aware that you need to contribute a perspective to a compat layer via snippet instead of a perspective to the perspective stack?

Thanks, I figured that out earlier today through various postings. However, the part that's also not document is how to get placeholders working. Thanks to the link you provided, I now made a bit more progress.

That's what I have in my fragment which sort of works:

The trick is to define a fragment which adds things to the "sharedElements" of "IDEWindow". However, I'm unsure if this approach is sane, i.e. will it create duplicate shared elements?

Could you import shared elements?

I don't know. The model editor in Neon does not give me an option in the drop-down to import a shared element.

Importing a "Part" does not work. There are none and/or the ones created by the compatibility layer are not visible to the model editor. I'm also not sure if the compatibility layer uses stable xmi ids that would work as stable references.

How did you do this? Did you right click on the project, then New -> Other... then what did you choose? Thanks. IS Eclipse supposed to generate an e4xmi for you?

Hi Gunnar, I am following your e4xmi to integrate Egit into my E4 project. But This method does not seem to work with Egit on 2020-09 version. Do you still able to make it work?

Thanks.
