DeltaX |
|
Scroll amount in the horizontal direction. A negative value scrolls to the left, and a positive value scrolls to the right. |
DeltaY |
|
Scroll amount in the vertical direction. A negative value scrolls toward the top, and a positive value scrolls toward the bottom. |
ScrollBy us an overridden method in TCustomGrid. No actions are performed in the method when both DeltaX and DeltaY contain 0 (zero).
ScrollBy calls ScrollWindowEx to perform the scrolling operation for the non-fixed client area on the control. It updates the visible grid area in the cached information for the control, and recalculates the scroll bar ranges.
ScrollBy is called from the TrySmoothScrollBy method, and occurs when scroll bar messages or mouse wheel events are handled for the grid control.
