Re: [eclipse-incubator-e4-dev] Initial discussion onthe'modelled'workben

Cool, I'm getting Paul to help me get
ste up so that we can chat 'offline' (I say "out of the Vortex"...;-).
While you're at it can you determine what a client would have to do to
add a new 'sub class' of the 'Stack' with additional 'custom' properties
? I'm giving you the heads up because that'll be the ffirst question I
expect to ask...;-).

Talk to you in a bit...

Hi,

In my current EricToTom-Transformation I've modeled it currently like this:

EPresentationModelElement              
   EStyle
    ^                
                     
 ^ ^
    |

                   |  
                     
  |
             EGUIElement x------------>
EStyleClass
                    
              0..1
