[news.eclipse.tools] Re: editor ruler action icon

[weisz@xxxxxxxxxx (Robert)]

Kai,

Actually, I was using the markerImageProvider until I read that it's
internal only, although it probably wouldn't have solved the problem of
changing the icon depending if the breakpoint is enabled or disabled, as
you are pointing out.

Looking at what JDT did triggered my first posting, after my head started
spinning :-), hoping that there is a simpler way of doing it that I simply
didn't know about...
Do you have any timetable for when this "looking into simplifying this"
might show up in a driver?  

Robert.
