[IDC Discussion] Should the RTSTRUCT show contours in the side panel if no contours are stored?

In #1896 I fixed the immediate issue presented by #1892, however we need to decide the best user experience for this case:

• The ROIContourSequence contains metadata about a specific ROINumber.
• No contours for that ROINumber are present in the StructureSetSequence.

At the moment I decided to show the metadata to the user, and warn with a notification when that the contours don’t exist when the user tries to jump.

However we could choose to hide the ROI Contours that have no related structures from the list entirely, so that only contours with actual StructureSet data are shown.

I personally think keeping the contour metadata in the list is better, as it indicates that the data may be broken/exported incorrectly from source, perhaps we should grey out the contours to indicate they have no data? What’s your opinion @fedorov @pieper ?

Yes, I think the approach you suggested is reasonable. Maybe those contours can be shown with “exclamation”/warning sign icon in the list, since we know while forming the list that they will not render?

Easily = Yes!
