I'm not sure if I'm posting this to the right group. If not, please
excuse me.

I've got two questions about EMF/GMF Editors, especially
EcoreDiagramEditors and EcoreEditors:
  
      

I'm not exactly sure what you're referring to?  The editors for editing
*.ecore resources?
    

First, I would like to get the EObjects which are currently selected in
an active EcoreDiagramEditor. Is there a way of doing this?
  
      

Editors generally provide a selection service you can use to determine
the current selection.  E.g., EMF generated editors implement
ISelectionProvider.
    

In the question about getting selected EObjects I was referring to the 
org.eclipse.emf.ecoretools.diagram.part.EcoreDiagramEditor which, 
unfortunately, does not implement the ISelectionProvider. For generated 
Ecore editors using this provider works perfectly. But, how can I get the 
EObjects which are selected in the diagram displayed by an 
EcoreDiagramEditor?
  

I think you can use getSite().getSelectionProvider().

Second, how can I set an EcoreEditor (tree editor) to dirty (leadings
to the asterics in the tab) after changing its contents from outside
programmatically.
      

You must use commands to make changes.
    

I retrieved the selected EObjects using ISelectionProvider.getSelection
and changed the objects. The changes are displayed in the editor
immediately. But how can I set the editor to dirty
from outside to force a "want to save"-question when closing.
  
      

You must use the editor's command stack.  IEditingDomainProvider
provides access to it.
    

Thanks for this hint! I'll change my implementation to make use of the 
command framework.

  

Thank you very much in advance,

Philip Langer
