Request information about Vector chart objects
The ability to cursor-pick on an object for the additional information that lies behind the object is an important part
of ECDIS capability. However, an unprocessed cursor pick, which does discriminate or interpret and merely dumps
on the interface panel all the information available at that point on the display, will normally result in pages of
unsorted and barely intelligible attribute information.
