[news.eclipse.platform.swt] Having trouble to make label decorator worki

[Julien <jdenet@xxxxxxxxxxxxx>]

Hello,


I don't succeed in implementing a Label decoration for a TreeViewer. I 
just need to have image decoration so I assume I only need a LightWeight 
decorator. I have defined it according to what I have understood from 
eclispe Help (Platform Plug-in Developer Guide > Programmer's Guide > 
Advanced workbench concepts > Decorators).

Here is what i have done:
in plugin.xml:

<extension
         point="org.eclipse.ui.decorators">
      <decorator
            icon="icons/question_ov.gif"
            id="azerty.decorator"
            label="label"
            lightweight="true"
            location="BOTTOM_RIGHT"
            state="false">
         <enablement>
            <objectClass
                  name="azerty.NavigationView$TreeObject">
            </objectClass>
         </enablement>
      </decorator>
   </extension>

I must be missing something. Does a complete example of this kind of 
implementation exists?

Regards,
Julien
