Mac Forum / Programming / CodeWarrior / January 2005

I have a problem which I don't understand:

I am using codeWarrior 9.3.

I am trying to select and open files of type PICT, regardless of the creator,
so, according to the documentation I use

 
err=NavCreateCooseFileDialog(&NavOptions,fileTypeListH,NULL,NULL,NULL,NULL,&outDi
alog);

The Nav options are basically the standard options.

The fileType list contains only 1 item for the PICT, and the generic component
signature:
 
  (*fileTypeListH)->osTypeCount=1;
  (*fileTypeListH)->componentSignature=kNavGenericSignature;
  (*fileTypeListH)->osType='PICT'

What happens is that only PICT files with the component signature equal to the
creator tag of the application are selected.  Other PICT files are dimmed and
cannot be selected, in particular PICT files of type 'ttxt' created by grabbing
a frame from an iMovie sequence.  I can verify with ResEdit that these fiels are
really of type 'PICT' and creator 'ttxt' but the Nav window will not make them
selectable.  I tried with NavCreateGetFileDialog and I get exactly the same
reults.

Why the
 
  (*fileTypeListH)->componentSignature=kNavGenericSignature;

doesn't seem to have an effect?

FURTHERMORE, if I opt for selecting ALL files, passing the list handle as NULL,
the when I select a PICT file with creator 'ttxt' (craeted with iMovie), after
doing

        err=AECountItems(&navReply->selection,&n);
        err = AEGetNthPtr(&navReply->selection, n,
                                   typeFSRef, &theKeyword,
                                   actualType,&fsref,   //fspec,
                                   sizeof(fsref),
                                   &actualSize);
       
                               
err=FSGetCatalogInfo(&fsref,kFSCatInfoGettableInfo,&cinfo,&uname,fspec,NULL);
         
err=FSGetCatalogInfo(&fsref,kFSCatInfoFinderInfo,&cinfo,&uname,fspec,NULL);

     err=FSpGetFInfo(fspec,&finfo);
 

I get a finfo.fdtype=0, not ='PICT' as it should be expected.

What am I doing wrong or not taking into consideration?

It works for any other combination of Type and Creator which I use.

Thanks
