Re: [e4-dev] Suggested Model adjustments - Add PerspectiveDescriptors to the model?
Thanks for the reply Paul.

I would like to convert the perspective extensions at startup to model elements. Currently we do this on request, i.e., if a users opens a perspective the extension point information is converted to an application model. Such a perspective is "active", i.e., the objects are created for it.

This creates the issue that we can for example not adjust the perspective switcher in the IDE to work on the application model.

What is our suggestion to contribute a perspective to the Eclipse IDE application model? 

Best regards, Lars

Hi Lars,

Hello,

In the current runtime application model of the IDE, we create perspectives based on the perspectives which were opened by the user or as default perspective.

I think the current model makes it difficult to migrate the existing extension point based definition of perspectives to the application model. 

We could use model snippets (for perspectives) to model this, but I think we should go for the same route as for ViewDescriptors or Toolbar and Menu contributions.

I don't agree.  We already have an implementation that saves perspectives as snippets.  Why wouldn't you enhance that?

The MPartDescriptors that in the model are really specializations of fragments because we needed very specific behaviour and didn't have the support for applying fragments in post-model-processing.  The toolbar and menu contributions are worse, we just didn't have another way to re-generate fragments on every "matching" creation (like adding a new MTrimmedWindow to the model should re-apply all relevant menu contributions, except we didn't have the proper fragment story and so it's done with hooks during rendering/post rendering).

Later,
PW
