Shape, Connection & Properties View [message #1272318]

Hello,

I have a problem with my implementation of my properties view for my graphical editor. The properties for Shape (EObject) is shown correctly. However, the properties for Connection (EReference) is not shown at all.

My adapter implementation is shown below:

public class GraphitiEditPartToIPropertySourceAdapterFactory implements
IAdapterFactory {

	public GraphitiEditPartToIPropertySourceAdapterFactory() {
		super();
	}

	public Object getAdapter(Object adaptableObject, @SuppressWarnings("rawtypes") Class adapterType) {
		if (IPropertySource.class.equals(adapterType)) {
			if (adaptableObject instanceof GraphitiConnectionEditPart) {
				GraphitiConnectionEditPart editPart = (GraphitiConnectionEditPart) adaptableObject;
				PictogramElement pictogramElement = editPart.getPictogramElement();
				Object object = editPart.getFeatureProvider().getBusinessObjectForPictogramElement(pictogramElement);
				if (object instanceof EReference) {
					return new EReferencePropertySource((EReference) object);
				} 
			} else if (adaptableObject instanceof GraphitiShapeEditPart && !(adaptableObject instanceof GraphitiConnectionEditPart)) {
				GraphitiShapeEditPart editPart = (GraphitiShapeEditPart) adaptableObject;
				PictogramElement pictogramElement = editPart.getPictogramElement();
				Object object = editPart.getFeatureProvider().getBusinessObjectForPictogramElement(pictogramElement);
				if (object instanceof EObject && !(object instanceof EReference)) {
					return new EClassPropertySource((EObject) object);
				}
			}
		}
		return null;
	}


	@SuppressWarnings("rawtypes")
	public Class[] getAdapterList() {
		return new Class[] { IPropertySource.class };
	}

}

Since I wanted the adapter to handle two types of objects, I chose the adaptableType as shown below:

<extension
         point="org.eclipse.core.runtime.adapters">
      <factory
            adaptableType="org.eclipse.gef.editparts.AbstractGraphicalEditPart"
            class="test.GraphitiEditPartToIPropertySourceAdapterFactory">
         <adapter
               type="org.eclipse.ui.views.properties.IPropertySource">
         </adapter>
      </factory>
   </extension>

As mentioned before, this implementation shows the properties of the shapes correctly but not the connections.

Can someone help me figure where I went wrong? If you require other files from my implementation let me know and I will post it. Thank you. Smile

For those who have this problem, I have found a solution.

The mistake I made was in adaptableType. I thought you could declare a adaptableType which was a superclass to both shape and connection such as org.eclipse.gef.editparts.AbstractGraphicalEditPart which does not work.

You need to create two adapters each adapting shape and connection separately like this:
shape adaptableType: org.eclipse.graphiti.ui.internal.parts.ContainerShapeEditPart
connection adaptableType: org.eclipse.graphiti.ui.internal.parts.FreeFormConnectionEditPart

   <extension
         point="org.eclipse.core.runtime.adapters">
      <factory
            adaptableType="org.eclipse.graphiti.ui.internal.parts.ContainerShapeEditPart"
            class="se.scania.yset.xmleditor.property.GraphitiEditPartToIPropertySourceAdapterFactory">
         <adapter
               type="org.eclipse.ui.views.properties.IPropertySource">
         </adapter>
      </factory>
      <factory
            adaptableType="org.eclipse.graphiti.ui.internal.parts.FreeFormConnectionEditPart"
            class="se.scania.yset.xmleditor.property.GraphitiEditPartToIPropertySourceAdapterFactory">
         <adapter
               type="org.eclipse.ui.views.properties.IPropertySource">
         </adapter>
      </factory>factory>
   </extension>

These two adapters can still be implemented using the same adapterfactory class.
