Re: [platform-text-dev] Line Highlighting

[Mary Kroening <mary@xxxxxxxx>]

Hi Kai,

Can you clarify your second paragraph a little more. I've implemented 
preference pages based on the model in the JDT. So I can set the 
preferences for each of the items in MarkerAnnotationPreferences as well as 
the appearance preferences. However, the annotation preferences do not work 
(the appearance ones do).

Given that I have my own preference store, do I need to override methods in 
TextEditor? Which ones?

Or do I have to add some kind of new extension point or extension related 
to the markerAnnotationSpecification point? That point mentions a schema in 
schema/markerAnnotationSpecification.exsd. But I cannot find that file. Can 
you clarify this a little more?

Thank you,
