OK, it's all clear until:
"take steps to ensure that one is used instead of the one provided
directly by the UML2 project"
Here's what I have in the .edit project generated by GMF:
protected void addXXXPropertyDescriptor(Object object) {
itemPropertyDescriptors.add
(createItemPropertyDescriptor
(((ComposeableAdapterFactory)adapterFactory).getRootAdapterF actory(),
getResourceLocator(),
getString("..."),
getString("...", "...", "..."),
XXXPackage.Literals.XXX,
true,
false,
false,
ItemPropertyDescriptor.GENERIC_VALUE_IMAGE,
null,
null));
}
I guess this is the part that sets which Adapter Factory is used:
((ComposeableAdapterFactory)adapterFactory).getRootAdapterFa ctory()
Should I just create my specialized Adapter Factory and pass it instead of
the one returned by getRootAdapterFactory()?

W.F.,
You could extend UMLs item provider adapter factory and change the
create adapter method for Property to use your own. You're showing a
specific property descriptor and it's certainly possible to modify the
label provider for a given property descriptor to show labels in a
specific way, but I didn't think that was your original question.

Yes, that's what I want to do: I have a specific drop-down list which
contains the Property elements and I want to change their labels there.
So is this a good way to do this:
protected void addXXXPropertyDescriptor(Object object) {
itemPropertyDescriptors.add
(createItemPropertyDescriptor
(new ComposedAdapterFactory(new MyOwnUMLItemProviderAdapterFactory),
getResourceLocator(),
getString("..."),
getString("...", "...", "..."),
XXXPackage.Literals.XXX,
true,
false,
false,
ItemPropertyDescriptor.GENERIC_VALUE_IMAGE,
null,
null));
}
I would have:
new ComposedAdapterFactory(new MyOwnUMLItemProviderAdapterFactory)
Or is there an easier way to change the labels?
I still have two problems:
- where to put the implementations of the specialized UML AdapterFactory
and specialized UML PropertyItemProvider in the GMF project structure?
- is it ok that I create a new AdapterFactory instance every time
addXXXPropertyDescriptor(Object object) is called? I think it's called
whenever the drop-down list is accessed.

WF,
Perhaps having a look at how ETypedElementItemProvider does something
similar will help so how to specialize just the label provider for a
given property.
protected void addETypePropertyDescriptor(Object object)
{
itemPropertyDescriptors.add
(new *ItemPropertyDescriptorWithUniqueChoiceOfValueLabels*
(((ComposeableAdapterFactory)adapterFactory).getRootAdapterF actory(),
getResourceLocator(),

Thanks for your help!
That's a very compact solution:
protected void addXXXPropertyDescriptor(Object object) {
itemPropertyDescriptors.add
(new ItemPropertyDescriptor
(((ComposeableAdapterFactory)adapterFactory).getRootAdapterF actory(),
getResourceLocator(),
getString("..."),
getString("...", "...", "..."),
XXXPackage.Literals.XXX,
true,
false,
false,
null,
null,
null) {
@Override
public IItemLabelProvider getLabelProvider(Object object) {
return new ItemDelegator(adapterFactory, resourceLocator) {
@Override
public String getText(Object object) {
if (object instanceof Property) {
return super.getText(object) + ((Property)
object).getClass_().getLabel();
} else {
return super.getText(object);
}
}
};
}
});
}

W.F.,
Pretty cool hey. There's almost always a nice elegant solution, if only
it were easier to find.
