SCROLLINFO structure (winuser.h)
The SCROLLINFO structure contains scroll bar parameters to be set by the SetScrollInfo function (or SBM_SETSCROLLINFO message), or retrieved by the GetScrollInfo function (or SBM_GETSCROLLINFO message).
Syntax
typedef struct tagSCROLLINFO {
UINT cbSize;
UINT fMask;
int nMin;
int nMax;
UINT nPage;
int nPos;
int nTrackPos;
} SCROLLINFO, *LPSCROLLINFO;
Members
cbSize
Type: UINT
Specifies the size, in bytes, of this structure. The caller must set this to sizeof(SCROLLINFO).
fMask
Type: UINT
Specifies the scroll bar parameters to set or retrieve. This member can be a combination of the following values:
nMin
Type: int
Specifies the minimum scrolling position.
nMax
Type: int
Specifies the maximum scrolling position.
nPage
Type: UINT
Specifies the page size, in device units. A scroll bar uses this value to determine the appropriate size of the proportional scroll box.
nPos
Type: int
Specifies the position of the scroll box.
nTrackPos
Type: int
Specifies the immediate position of a scroll box that the user is dragging. An application can retrieve this value while processing the SB_THUMBTRACK request code. An application cannot set the immediate scroll position; the SetScrollInfo function ignores this member.
