Conditional Formatting for values calculated by the IGroupBySummaryProvider [message #1494773]

I'm having trouble trying to add conditional formatting for values calculated by the IGroupBySummaryProvider. I'm trying to add a label that changes the foreground color to red for negative numbers. For normal data rows, I was able to get this working by comparing the cell's data value in an ILabelAccumulator. For GroupByObjects however, I overflow my stack when I try to get the aggregated value from the GroupByDataLayer in an ILabelAccumulator since the GroupByDataLayer calls the ILabelAccumulator itself.

Is there anyway implement this behavior in the current architecture?

Thanks

Doesn't look like that is possible at the moment.

Please create a ticket for this. I will have a look at the GroupBy stuff in general soon.

Done. https://bugs.eclipse.org/bugs/show_bug.cgi?id=453874

Let me know if you'd like any help implementing any of the remaining enhancements for the group by feature.

Thanks! I will let you know if there is something you can help me with. Would like to see more support from the community. Smile

I guess I need to think about a whole refactoring of the GroupByObject itself. Maybe it needs to have more states than simply the value representation, like storing the summary provider for each column so it doesn't need to be requested all the time. Although I'm not sure if that arises other issues. Difficult task!
