Something I use is the IChildCreationExtender interface.
You can define a concrete implementation in a plugin.xml
<extension
point="org.eclipse.emf.edit.childCreationExtenders">
<extender
class="MyCoolChildCreationExtender"
uri="http://package uri for your package holding the objects">
</extender>
The extender is consulted when selecting an object in your view,
so instead of having static definitions in your
collecNewChildDescriptors you can make it dynamic by considering your
model status or UI options. I prefer this way, as the ItemProviders are
difficult IMHO to be fed with the model or UI stuff.

Of course. You can look in your generated XyzActionBarContributor to
see how it populates these menus.
Thx Ed,
I had a look inside this class, but could only see how the Child and Sibling menus are realized. I'm wondering how I could remove the Wizard, Run as or Debug as entries?

Thx Christophe,
are there any examples or tutorials how to use this interface. Or maybe any running example so that I can see how these interfaces looks like?
Cheers,

Phil,
I'm not sure how to remove things contributed from the base frameworks.
You'll notice that even in the explorer views, such menu items always
appear.
