Re: AW: AW: AW: AW: AW: [ve-dev] Overriding the Property-Editor inaSubcl

[Rich Kulp <richkulp@xxxxxxxxxx>]

Hi Peter,

Yeah, I was afraid of that. :-(  Both
features still exist on the EMF class. It is just that when you look up
the feature by name it will find the first feature from the bottom up,
which means it finds the one from your subclass when lookup by name.

I think you may need to also supply
a PropertySourceAdapter implementation for your RButton that inherits from
BeanPropertySourceAdapter, and it overrides just one method:

protected
boolean
includeFeature(EStructuralFeature sfeature) {
         
      
        //
Do not include the "text" feature from the base ULCBean.
        if
(sfeature.getName().equals("text")
&& sfeature.getEContainingClass().getName().equals("ULCButton")
         
      return
false;
        else
       
         
      return
super.includeFeature(sfeature);
}


Thanks,
Rich

Hi Rich!

Thanks for your patience with me and your help.

You were right, I forgot to declare 2 namespaces in the header...

I think, we're getting closer... I have now the
funny thing that I have TWO "text" properties in the
property sheet for my RButton instance 
and on the first one I've got my editor! :-) (see attachement).

any ideas ?

best regards,
peter
