Overriding getBackground in the generated itemprovider [message #426572]

I am overriding the ItemProviderAdapter.getBackground() method in my
generated itemprovider and I would like to know if there is a way to
access it via the EObject adapter like when one want to access the getText
and getImage methods.

IItemLabelProvider itemLabelProvider =
(IItemLabelProvider)adapterFactory.adapt(object, IItemLabelProvider.class);
itemLabelProvider.getImage(object)

In other words, is there way I can obtain the ItemProviderAdapter the same
way as shown above for the IItemLabelProvider?

TIA!

Like IItemColorProvider. Note that in the GenModel's Edit properties
you can enable Color Providers (not to mention Font and Table). This
should update the registration in the plugin.xml but since that doesn't
merge, you have to update it manual or delete it and regenerate it...

Ben,

I should mention too, that AdapterFactoryLabelProvider of course has
convenient methods to hide all the details...
