Use PartDescriptor to create an input part [message #1097228]

Hi,

I've been looking at the PartServiceImpl and it seems like one can use PartDescriptor in the e4xmi only to create MPart instances, and not MInputPart.

Is there a way to use PartDescriptors to create MInputPart templates?

Thanks a lot!

Sébastien

I don't know of any.
It seems to me that MInputPart (at least for now) has very limited functionality. All it manages to achieve, is to confuse users and make them think that MPart, MInputPart are the new ViewPart, EditorPart.

One idea is to give up MInputPart in your application and just use MPart. It can be saved and have dirtyable property just as MInputPart. Instead of MInputPart::getInputUri():String you can use persisted state
(MPart::getPersistedState() returns a map).

Second idea is to just create it manually like that:

 MInputPart editor = MBasicFactory.INSTANCE.createInputPart();
 editor.setContributionURI(...);
 editor.setCloseable(true);
 URI inputURI = URI.createFileURI(...);
 editor.setLabel(...);
 editor.setInputURI(...);
 editor.setIconURI(...);
 /* add new editor to editor stack */
 MPartStack partStack = (MPartStack) modelService.find(
                editorStackID, application);
 partStack.getChildren().add(editor);
 partService.activate(editor, true);

You can probably use model service to read needed labels and URI's from some kind of snippet, so you would still be able to keep this information in application model.

We're in the process of deprecating MInputPart so using MPart is the correct approach. We're looking into providing an MEditorDescriptor in Luna to cover off the logic required to map inputs onto the correct editor implementation.
