published property TControlScrollBar.Increment : TScrollBarInc |
Increment is a TScrollBarInc property which indicates the amount the client area in the associated control is scrolled when the Up or Down navigation arrows on the scroll bar are clicked. The default value is 8.
The value in Increment may be automatically recalculated in the UpdateScrollBar method when the Smooth property is enabled and the associated control is a TScrollingWinControl descendant. This is done to ensure that Increment contains 10% of the value for the Page property.
Increment is used in the ScrollHandler method when updating the Position property for scroll bar messages received in the control.
