//
//  Author:     Harrison Ainsworth
//  Date:       06/99
//  Purpose:    represent and contain a gadget specifically for selecting bias/gain choices. 
//              intended to enable easier addition of such a gadget to various toolbars.
//              it handles messages generated by user interaction with the windows gadget, and then
//              sends out commit or slider-set messages (containing the chosen values) to its owning 
//              infobar.
//  Implemen-   depends on a InformationBarOp and valid gadgetID, bubbleID and statusID.
//  tation:     
//  Invariants: pOwningBar_m is valid, 
//              GadgetID_m is valid
//              BubbleID_m is valid
//              StatusID_m is valid
