How to add file annotation?

Hi,

My question is how to annotate filename, I mean, a red line under the filename which have error.

On my custom language project, i am using this code:

TextRange range = new TextRange(element.getTextRange().getStartOffset(),
element.getTextRange().getEndOffset());
holder.createErrorAnnotation(range, "ERROR");

The annotation in the context is ok, there  will be a red line under the words. But in the project view, there is not any annotation under filename.

Thanks in advance.
