I offer here an extended version of TScrollBox (VCL) which supports an
OnScroll event – the idea originally came from a
in the Delphi-Praxis forum. You can use it like the normal TScrollBox
with this further event. In the OnScroll event you have access to axis
which has been changed: axVertical, axHorzontal.
