[jdt-ui-dev] Overrides for Interface implementors, debug overrides?

["Kaspar von Gunten" <Kaspar.vonGunten@xxxxxxxxxx>]

Hi

I have two general questions about .override files and I hope someone
here can answer it for me.

Q1: How can I check if overrides are applied for a certain component in
VE (or in which order)? I.e. test if I configured everything correctly?

The background of this question is that I have a (visual) class
structure like this:

+java.lang.Object
	+foo.Container
     		+bar.MyContainer implements acme.ISpecialContainer

		+baz.MyContainer implements acme.ISpecialContainer

Q2: If I have an override file for foo.Container: Can I then define an
override for acme.ISpecialContainer which will override/extend the
foo.Container override and then be applied to all implementations of
ISpecialContainer?

I would like the following behavior:

- own icon for ISpecialContainer
- forbid to add children to ISpecialContainer in VE

I have defined an own GraphicalEditPart and an own ContainerPolicy
(which just returns UnexecutableCommand.INSTANCE in primAddCommand() and
primCreateCommand())

--- code start ---
public class SpecialContainerGraphicalEditPart extends
ContainerGraphicalEditPart
{
...
  @Override
  protected ContainerPolicy createContainerPolicy()
  {
    EditDomain domain = EditDomain.getEditDomain(this);
    return new RefuseAllChildrenContainerPolicy(domain);
  }
...
}
--- code end ---

Which is referenced in an override of
overrides/acme/ISpecialContainer.override:

--- override start ---
<?xml version="1.0" encoding="UTF-8"?>

    xsi:type="org.eclipse.ve.internal.cde.utility:GIFFileGraphic"/>
</objectsToAttach>
</change:ChangeDescription>
--- override end ---

However, this does not seem to work. How can I debug this?

Any help is appreciated!

Thanks,
Kaspar
