Hi All,

I am trying to replace renderer for 'org.eclipse.emf.ecp.view.spi.model.VControl'. I've created new plugin and configured extension point like below:

<plugin>
   <extension
         point="org.eclipse.emf.ecp.ui.view.swt.renderers">
      <renderer
            element="org.eclipse.emf.ecp.view.spi.model.VControl"
            renderer="org.leszyk.simple.groupgrid.swt.SWTControlRenderer">
      </renderer>
   </extension>

However it doesn't work. When debugging in SWTRendererFactory I see clearly that my renderer is discovered and initialized before the one provided by ECP itself. As they are stored in hashmap, the one provided by me is effectively replaced by this provided by ECP. It seems that in the renderer extention point I can't use staticTest and priorities section (as it is with control). Any hints?

Thank You!
Dominik

Hi Dominik,
In order to replace an existing renderer you have to use this extension point: org.eclipse.emf.ecp.ui.view.swt.customSWTRenderers

Custom Renderers are always used before the "normal" renderers.

In Version 1.3 on which we are currently working, we added tester with priorities to renderer. This way you will be able to control which renderer to replace very accurate, just like controls.

Cheers,
Eugen

Hi Eugen,

Thanks for reply.

We're using version 1.2 and it seems that the features you're describing doesn't exist anymore. I mean that extension point org.eclipse.emf.ecp.ui.view.swt.customSWTRenderers does exist but there is nowhere a code that would process it. However such code exists in version 1.1.1 in SWTRenderer class (AFAIR). Unfortunately it's not possible for us to downgrade:) We will wait for 1.3 and support of priorities in renderers.

Cheers,
Dominik
