IB_Edit (and therefore IB_Date) have their button defined in code in
IBC_Edit.IMP.

IB_LookupCombo uses a specially derived and embedded button component,
defined in IBG_LookupCombo.IMP.

You may need to ask Jason to make a few of the functions virtual or
dynamic to allow the derivations you will want.
