Archi development issue
« on: September 10, 2017, 13:38:37 PM »
Dear Archi community,

For a research program I am adding 2 new relationship concepts. The first being a copy of the aggregation relationship went smooth; the second (also a copy of aggregation) gives me an issue. The problem is that the added png figure for the Palette does not show up and using the new relation via the magic connector gives the following error:

Can somebody give me a hint for the location to solve? Thank you.

Kind regards,

Hi Richard,


Here's an old set of instructions:

Edit: way out of date!

Actually I think that method is way out of date.   ???

The UIProvider class should look like this one:

Code: [Select]
public class MyAggregationRelationshipUIProvider extends AbstractArchimateRelationshipUIProvider {

    public EClass providerFor() {
        return IArchimatePackage.eINSTANCE.getMyAggregationRelationship();
    }
   
    @Override
    public EditPart createEditPart() {
        return new ArchimateRelationshipEditPart(MyAggregationConnectionFigure.class);
    }

    @Override
    public String getDefaultName() {
        return "My Relationship";
    }

    @Override
    public Image getImage() {
        return IArchiImages.ImageFactory.getImage(IArchiImages.ICON_MY_AGGREGATION_RELATION);
    }

    @Override
    public ImageDescriptor getImageDescriptor() {
        return IArchiImages.ImageFactory.getImageDescriptor(IArchiImages.ICON_MY_AGGREGATION_RELATION);
    }
}


And should be registered in the plugin.xml as a objectUIProvider.

Thank you.

In fact the UIProvider class mentioned in the developer resource looks ok to me; at least this is the same structure I got from Github.

I will have a check.
