Started

The probable right function to use is (copied from XCode documentation) :

HIWindowGetProxyFSRef Obtains the FSRef used to determine the proxy icon for a window.

OSStatus HIWindowGetProxyFSRef (
  WindowRef inWindow,
  FSRef * outRef
);

Parameters inWindow The window whose proxy FSRef is to be obtained.

outRef On exit, the FSRef for the window’s proxy icon.

Return Value A result code. See “Window Manager Result Codes”.

Discussion If the specified window’s proxy icon has been specified using HIWindowSetProxyFSRef or SetWindowProxyAlias, HIWindowGetProxyFSRef returns noErr and a valid FSRef for the window’s proxy icon. If the window has no proxy icon, or if the icon was specified by calling SetWindowProxyCreatorAndType or SetWindowProxyIcon, this function returns an error.

Availability Available in Mac OS X v10.4 and later. Declared In MacWindows.h

Sample code from http://developer.apple.com/samplecode/MovieVideoChart/listing3.html :

static OSStatus setWindowTitleAndProxyFromFSRef( WindowRef window, FSRef *fileRef )
{
    OSStatus err = noErr;
  HFSUniStr255 name;
  CFStringRef fileName = NULL;
  
  err = FSGetCatalogInfo( fileRef, 0, NULL, &name, NULL, NULL );
    require_noerr( err, CantGetInfo );
  
  fileName = CFStringCreateWithCharacters( kCFAllocatorDefault, name.unicode, name.length );
  SetWindowTitleWithCFString( window, fileName );
  HIWindowSetProxyFSRef( window, fileRef );
  SetWindowModified( window, false );

CantGetInfo:
  if( fileName )
    CFRelease( fileName );
  return err;
}
