I'm writing a little program that needs to prompt the user to select a 
directory using SFGetFile.  I once saw a DA (Virus Detective) that did 
just this, and have a question about how one implements a "Directory"
button.  

Currently, I'm adding a custom "Directory" button to SFGetFile which 
allows the user to return the selected directory name.  (ie.  "Open" 
descends into the directory while "Directory" returns with the selected 
directory name).  My current routine (quite a hack) installs a dialog 
filter proc using SFPGetFile.  It looks for a hit on the "Directory" 
button, returning an "Open" and then a "Cancel" to the SFGetFile filter 
proc when it gets one.  This effectively descends into the selected 
directory and then exits, so I can subsequently use the values in the 
SFSaveDisk and CurDirStore globals to find out what the selected 
directory was.  This works, but is a bit unsightly since the user 
actually sees the SFGetFile dialog descending into the 
selected directory before quitting.

How do I do this smoothly??  Is there another system global (which I 
know I'm not supposed to use) which points to the selected string in 
the SFGetFile dialog?  Will the author of Virus Detective help me out 
on this one?  I don't remember his code doing this (though I guess I 
could've just missed it - no, any _good_ programmer could think up a 
better way :-)
