[news.eclipse.newcomer] working with content in IWorkbenchWindowActionDe

[Flo Lautenbacher <PrinceGecko@xxxxxxxx>]

Hi,

I´m building an Eclipse Plugin and want to add an action to a menu where 
I can work with the content (graphical, GEF) of my document.
I started with the Hello-World example and want to bring up a window 
with the name of the selected element (editpart) of my content window.
Is there a sample where I might find how to access the content?
I tried 
MyPlugin.getDefault().getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor().getEditorInput().getName();
but there I won´t get the object of the underlying model, but only the 
filename, where the object is stored.

Thanks for any help in advance.

Flo
