TCustomMemo.ScrollBy procedure
Scrolls the visible area in the control by the specified amounts.
Declaration

DeltaX | Amount to scroll horizontally. |
DeltaY | Amount to scroll vertically. |
Description
ScrollBy is an overridden method in
TCustomMemo used to
scroll the visible area for the control by the specified amounts.
DeltaX and
DeltaY contain the number of pixels the
content in the control is scrolled. DeltaX is applied to the horizontal
position. DeltaY is applied to the vertical position. A positive value means
that he control scrolls towards its bottom or right (respectively).
Conversely, a negative value scrolls the content towards its top or left.
ScrollBy calls the ScrollBy_WS method in the ancestor class. It
essentially replaces the method in the ancestor with the same name, and does
not call the inherited method.
