I found the following in ImageCompression.h:

pascal void SFPGetFilePreview(Point where,
    ConstStr255Param prompt,
    FileFilterProcPtr fileFilter,
    short numTypes,
    SFTypeList typeList,
    DlgHookProcPtr dlgHook,
    SFReply *reply,
    short dlgID,
    ModalFilterProcPtr filterProc)
= {0x303C,0x42,0xAAA3};

which could be defined as:

'============================================================
CLEAR LOCAL MODE
'pascal void SFPGetFilePreview(Point where,
'                       ConstStr255Param prompt,
'                       FileFilterProcPtr fileFilter,
'                       short numTypes,
'                       SFTypeList typeList,
'                       DlgHookProcPtr dlgHook,
'                       SFReply *reply,
'                       short dlgID,
'                       ModalFilterProcPtr filterProc)
' = {0x303C,0x42,0xAAA3};
LOCAL FN SFPGetFilePreview(where&,@prompt&, fileFilter&, numTypes%, typeList&, 
dlgHook&, sfReply&, dlgID%, filterProc&)
    '--------------------------------------------------------
    `
    `   MOVE.L ^where&, -(sp)        ;point
    `   MOVE.L ^prompt&, -(sp)       ;prompt string address
    `   MOVE.L ^fileFilter&,-(sp)    ;fileFilter procPtr
    `   MOVE.W ^numTypes%, -(sp)     ;number of file types
    `   MOVE.L ^typeList&,-(sp)      ;array address of 4 longs (DIM myTypes&(3),
pass as @myTypes&(0))
    `   MOVE.L ^dlgHook&, -(sp)      ;dialog hook routine ptr
    `   MOVE.L ^sfReply&, -(sp)      ;address of 88 byte StandardFileReply 
record
    `   MOVE.W ^dlgID, -(sp)         ;dialog ID
    `   MOVE.L ^filterProc&, -(sp)   ;dialog filterproc
    `   DC.W    $303C,$0042,$AAA3     ;trap number
    `
END FN

untested, and I don't have an example or any documentation on usage.

I recently read a section of a book about using the SFPGetFile (using 
CodeWarrior) and another toolbox call similarly named (SFPGetFilePreview?).

I don't think it was a QT related call as much as it was just a ROM call that 
loaded a PICT resource if it exists in the selected file for a preview.

I guess this doesn't help much, but there it is.
