Positioning IDecorator in different PictogramElement [message #1709633]

When using getDecorators(...) method is it possible to instruct decorator to be drawn in another PictogramElement? Here is my use case:

I have a ContainerShape that is marked as default by green check image:

User can double-click on this image and make this Shape non-default, and thus a code in getDecorators(...) method triggers decorator to be drawn:

This decorator is drawn in the PE that triggered this event, which is fine, but for my visual representation I'd like decorator to be drawn in another PE:

Is this something that is doable?

Regards,
Alex

Alex,

the method getDecorators is triggered for all pictogram elements on the diagram when the decorators are refreshed. Can you return the decorator only for the other PE instead of the original one? Unfortunatly I cannot follow your Googleusercontent links as they are not clickable or copyable...

HTH,
Michael

Thanks Michael,

I updated by original post. Not sure what happened with those images, I think Google Photos removes share after some period of time.

I tried refreshing decorators, but decorators did not refresh for all PEs when I executed getDiagramBehavior().refreshRenderingDecorators(getDiagram()); in ICustomFeature that is being returned in getDoubleClickFeature(...) of DefaultToolBehaviorProvider. What worked for me was executing getDiagramBehavior().refreshRenderingDecorators(containerToBeUpdated); where containerToBeUpdated is the PE that I wanted decorator to appear, and that worked.

Regards,
Alex

Alex,

the call to refreshRenderingDecorators will update the decoratos for the given PE only, e.g. it is not recursive.
