TAdvPanel index

How does one use the Index property of TAdvPanel?  I was thinking it was the index of the panel in a TAdvPanelGroup, however it seems to always be 0.

I can see that index is updated when inserting a panel.  I was dynamically creating the objects and not calling the insert method.  I'll change my code and perhaps this will answer my question!

Index is indeed used for ordering of panels within TAdvPanelGroup.
