Have a look at ETypedElementItemProvider.getComposedImage.

Ed,
Where to use it ?
I've looked at it but I don't know where exactly should I use this method.


I've the generated item provider adapters for all classes ( edit plugin)

should I use this in getImage method ? also, this class ETypedElementItemProvider where to extend it or what to change in the current generated model.


all I wanted to add flag icon on an existing icon upon if condition.

You don't use it, you look at how it works.

You'll want to specialize your getImage method to use ComposedImage.

Much like we want to add multiplicity decorations to a basic image...

Great, I went through it, and I reached something , wanted to share it with you.

In the edit plugin I override the method overlayImage which is used in each getImage method.

and used it easily by setting the image in it with the one i wanted to add on the original image. so, task was done there.

 protected Object overlayImage(Object object, Object image)
	  {
	  
	      List<Object> images = new ArrayList<Object>(2);
	      images.add(image);
	      images.add(getResourceLocator().getImage("full/obj16/requiredImagetoBeAddedOnOriginal"));
	      image = new ComposedImage(images);
	    
	    return image;
	  }


Thanks Ed.

That method is intended to adding the "controlled object" overlay so
reusing it for something else will disable it for that purpose. As you
can see, that method too simply uses ComposedImage so you could add your
own utility method just like that...

Yes I disabled its default action for a certain class which I wanted to add decoration for. as I don't need to track the controlled object thing in my program.
but it still affects the rest of classes.

this was very helpful.

Thanks!
