hello simon,

The icons stored in EMF-Edit plugin are also used for the GMF-editor. So
changing this would also change the GMF-editor appearance.

Simon -

you should also disable the generation of default icons in the genmodel
(edit section) to avoid your custom icons from being overwritten. I find
this particularly annoying, as you are forced to mix generated stuff
with manually changed things.

Note that GMF gets the generated LabelItemProvider directly and not
using the extension point. So you cannot even avoid generating the
EMF.edit plug-in and provide your own LabelItemProvider instead.

Unfortunately, I did not get an answer to my previous post on that topic.
(see news://news.eclipse.org:119/fpn0jn$6mu$1@build.eclipse.org)

Regards
Jan

We are using some aspectj in the edit plugin to overcome this restriction.

The IconFinder uses the class of the object to find the icon. the generated
icon will be used when no custom icon could be found.

public aspect EditorDecoration {
// customize item icon
pointcut getImage(Object item) :
execution( public Object *..*ItemProvider.getImage(Object) )
&& args( item );

Object around( Object item ) : getImage( item ) {
Object imageURL = IconFinder.getImageURL( item );
if (imageURL != null)
return imageURL;
else
return proceed( item );
}
}
