File Filter Functions(IM:Q)

File Filter Functions
A file filter function filters the files that are displayed to the user in a dialog box. You specify this function in the fileFilter parameter of the SFGetFilePreview, StandardGetFilePreview, and CustomGetFilePreview routines. If this parameter is not nil, SFGetFilePreview calls the function for each file to determine whether to display the file to the user. The SFGetFilePreview function supplies you with the information it receives from the File Manager's GetFileInfo routine (see Inside Macintosh: Files for more information).
