ScrollAmount enumeration (uiautomationcore.h)

Contains values that specify the direction and distance to scroll.

Syntax

typedef enum ScrollAmount {
  ScrollAmount_LargeDecrement = 0,
  ScrollAmount_SmallDecrement = 1,
  ScrollAmount_NoAmount = 2,
  ScrollAmount_LargeIncrement = 3,
  ScrollAmount_SmallIncrement = 4
} ;

Constants

ScrollAmount_LargeDecrement Value: 0 Scrolling is done in large decrements, equivalent to pressing the PAGE UP key or clicking on a blank part of a scroll bar. If one page up is not a relevant amount for the control and no scroll bar exists, the value represents an amount equal to the current visible window.
ScrollAmount_SmallDecrement Value: 1 Scrolling is done in small decrements, equivalent to pressing an arrow key or clicking the arrow button on a scroll bar.
ScrollAmount_NoAmount Value: 2 No scrolling is done.
ScrollAmount_LargeIncrement Value: 3 Scrolling is done in large increments, equivalent to pressing the PAGE DOWN or PAGE UP key or clicking on a blank part of a scroll bar. If one page is not a relevant amount for the control and no scroll bar exists, the value represents an amount equal to the current visible window.
ScrollAmount_SmallIncrement Value: 4 Scrolling is done in small increments, equivalent to pressing an arrow key or clicking the arrow button on a scroll bar.
