Sender is for "OnEvent" handlers so you can find out which (typically VCL control) was responsible for invoking the event. Not likely to be of much use if you are just calling methods that do some internal operation on your own object. You don't need to have the Sender parameter, even for OnEvent handlers if you are using them for your own purposes.
