Return value

TRUE if the application is handling the hot item change itself; otherwise FALSE.

Remarks

The NMTBWRAPHOTITEM structure must be defined by the application as follows:

typedef struct tagNMTBWRAPHOTITEM {
    NMHDR hdr;
    int iStart;
    int iDir;
    UINT nReason;       // HICF_* flags
} NMTBWRAPHOTITEM, *LPNMTBWRAPHOTITEM;
