Hi NG,
I want to open a subclass of FilteredItemsSelectionDialog where I can
select one of the elements which are all EObjects. For better labels in
the dialog I want to display the text and image of the EObjects as it is
returned by its item provider. If such an item provider doesn't exist
then the default text and image should be displayed. Can you give me a
hint how to achieve this?
best regards,
Gilbert

Yes, exactly that is what I want. I could solve it with the following
snippet:
EObject object = (EObject) element;
EcoreItemProviderAdapterFactory factory = new
EcoreItemProviderAdapterFactory();
if(factory.isFactoryForType(IItemLabelProvider.class)){
IItemLabelProvider labelProvider = (IItemLabelProvider)
factory.adapt(object, IItemLabelProvider.class);
if(labelProvider != null){
return labelProvider.getText(object);
}
}
Is this a convenient method to do this?

Gilbert,
Wrap the item provider adapter factory with an AdapterFactoryLabelProvider.
