Hello !
I wish to decorate elements in all kind of EMF editors. Is it possible ?
I have found org.eclipse.ui.decorators extension point to decorate
IResource in the package explorer (but it works only on package explorer ?).
I have alse found org.eclipse.ui.startup extension point but I have to
list the editors packages in the "earlyStartup" method and I can't list
all the editors I want.
public class Startup implements IStartup {
/**
* Initializes me.
*/
public Startup() {
super();
}
/**
* Install the validator.
*/
public void earlyStartup() {
EValidator.Registry.INSTANCE.put(FooPackage.eINSTANCE,
new EValidatorAdapter());
EValidator.Registry.INSTANCE.put(Foo2Package.eINSTANCE,
new EValidatorAdapter());
...
}
}
Thanks.
Nathalie Lépine, Obeo.

Nathalie,
I'm not sure what that means exactly, but note that decoration could
happen directly via a specialized AdapterFactoryLabelProvider that
decorates the normal results you'd get from the item provider. I.e.,
it's not necessary to modify the item providers themselves to use this
technique. And of course the AdapterFactoryLabelProvider constructed
using a ComposedAdapterFactory that in turn is constructed with
ComposedAdapterFactory.Registry.INSTANCE could be used to produce labels
for any model that has registered its item providers...
