TAdvancedPolyList - TTextItem

Hi There !

How to get TTextItem Caption Height ?
Regards

See:

No, it's height of WHOLE control,
I dynamically place another control in TTextItem and i'd like to know "top" of that control, since ttextItem
caption might be 1,2 or more lines . Hence need of Caption Height only.
Regards

Or maybe there is control more suited to hold another controls ( TAdvRichEdit ) in TadvPolyLists ?
