You give a Range
that is longer than the control's client width/height. To scroll, you can set its position. Eg:
HorzScrollBar.Range := ClientWidth * 2;
HorzScrollBar.Position := HorzScrollBar.Range - ClientWidth;

I have a custom component (TScrollingWinControl). But the scroll bars never appare, how do you show scroll bars on this component? Do you have to create a procedure to read them in or are they all ready there?
