RealIndex is an Integer function used to get the ordinal position in the collection for the visible column specified in Index. It is provided to maintain compatibility with older versions of the LCL, where Items was used to access column instances with their visible property set to True. Current LCL version do not have this limitation; they access the collection directly.
The return value is set to the value in the Index argument when it is a value position in the collection. Otherwise, the return value is set to -1.
RealIndex is called from the ColumnIndexFromGridColumn method in TCustomGrid when its Columns collection has been enabled.
