How to decorate an image? [message #333006]

Hello,

I'm using a TreeViewer together with ColumnLabelProviders. I've found out
that there is no DecoratingLabelProvider for columns and therefore I've to
implement decorating myself.

My question is if I have to write the decorating code myself, or is there
a smart helper somewhere?

Id I call:
decorator.decorateImage(image, element);

and get into my decorator it looks like this:
@Override
public Image decorateImage(Image image, Object element) {
// TODO Auto-generated method stub
return null;
}

At this part I would like to get the job done by someone else :)

Thanks

Btw.: As of Eclipse 3.4 you have DecoratingStyledCellLabelProvider
available.

Thank you Daniel!

DecoratingStyledCellLabelProvider needs a ILabelDecorator in its
contructor. Does'nt I end up at exactly the same possition where I was
when using it?

Or is there a smart way to get the labeldecorator and decoration context?
Its somehow hard to finde examples even using google.
