Hi,

I have an emf object and I want to get it's relevant item provider to
get text/label and image.
There are number of emf models in the system and they are not known in
advance.

I was thinking that may be if I can use that object to get its adapter
which then I can cast to IItemLabelProvider and then call getText() &
getImage() method on that.

Is there someway to do that? I was looking in
ComposedAdapterFactory.Descriptor.Registry.INSTANCE

Thanks for your help.

Yes, use that as an argument to creating a new ComposedAdapterFactory,
wrap it in a AdapterFactoryLabelProvider, and you should be all set.

Thanks Ed. It worked:

AdapterFactoryLabelProvider labelFactory = new
AdapterFactoryLabelProvider(new
ComposedAdapterFactory(EMFEditPlugin.getComposedAdapterFacto ryDescriptorRegistry()));

labelFactory.getText(myObj);
