Custom label provider for Model Navigator view [message #1745430]

Hello, Papyrus community!

I want to customize standard papyrus label provider to add custom icons to UML model, depending on profile, profile attributes, model elements and user preferences.

I've tried to use CNF <override> mechanics, but it looks like Papyrus does not respect CNF registrations of label providers and instead always uses it's own implementation.

So, there sure should be a way to use custom/delegating label provider to use custom icons for some element types and delegate to the default provider for the rest.

So, the question is how to register a custom label provider in Model Elements view using Papyrus API?

Many thanks in advance!

Hi, Leonid,

Papyrus offers a few different mechanisms for customization of the icons in the Model Explorer. Firstly, if an element has a stereotype applied that has a custom icon defined in the profile, then that icon should be used.

But, for more flexibility, the Papyrus APIs include a Label Provider Service. Search references in plugin.xml to the org.eclipse.papyrus.infra.services.labelprovider.labelProvider extension point for examples of how to register a label provider with this service and how to give it priority over other providers and filter its applicability to specific elements in the Model Explorer.

HTH,

Christian
