TLMDListBox callback "Sender" value

I have a TLMDListBox with an on-click callback. 

from header: TLMDListBox *TankAdjustmentList;

callback: void __fastcall TMachine2MainForm::TankAdjustmentListClick(TObject *Sender)

The "Sender" value appears to point to a TLMDExtListBox rather than the TLMDListBox component. Is this correct?

I deduced that by checking the value of Sender against values shown in Debug for the TLMDListBox control. Is there any way to get back to the TLMDListBox pointer from Sender?

    Yes. TLMDListBox contains the inner listbox control. It is the same control you can reference via TLMDListBox.LB parameter.

    Sure. It is the parent/owner of the sender.
