SCROLLINFO (Windows Embedded CE 6.0)

1/6/2010

This structure contains scroll bar parameters to be set by the SetScrollInfo function or retrieved by the GetScrollInfo function.

Syntax

typedef struct tagSCROLLINFO {
  UINT cbSize; 
  UINT fMask; 
  int nMin; 
  int nMax; 
  UINT nPage; 
  int nPos; 
  int nTrackPos; 
} SCROLLINFO; 
typedef SCROLLINFO FAR* LPSCROLLINFO; 

Members

• cbSize
  Specifies the size, in bytes, of this structure.

• fMask
  Specifies the scroll bar parameters to set or retrieve. It can be a combination of the following values.

  Value	Description
  SIF_ALL	Combination of SIF_PAGE, SIF_POS, SIF_RANGE, and SIF_TRACKPOS.
  SIF_DISABLENOSCROLL	This value is used only when setting a scroll bar's parameters. If the scroll bar's new parameters make the scroll bar unnecessary, disable the scroll bar instead of removing it.
  SIF_PAGE	The nPage member contains the page size for a proportional scroll bar.
  SIF_POS	The nPos member contains the scroll box position, which is not updated while the user drags the scroll box.
  SIF_RANGE	The nMin and nMax members contain the minimum and maximum values for the scrolling range.
  SIF_TRACKPOS	The nTrackPos member contains the current position of the scroll box while the user is dragging it.

• nMin
  Specifies the minimum scrolling position.

• nMax
  Specifies the maximum scrolling position.

• nPage
  Specifies the page size. A scroll bar uses this value to determine the appropriate size of the proportional scroll box.

• nPos
  Specifies the position of the scroll box.

• nTrackPos
  Specifies the immediate position of a scroll box that the user is dragging. An application can retrieve this value while processing the SB_THUMBTRACK message. An application cannot set the immediate scroll position; the SetScrollInfo function ignores this member.
