I want to use FileNameSetter to create a button which behaves in the
expected way for implementing a Save As... functionality.
So I did this
FileNameSetter[Dynamic[filename], "Save", Appearance -> "Save File..."]
This is fine, except that I can't find any way to determine whether the "OK"
or "Cancel" button is used to exit the file dialog box. It is not sufficient
to determine if the value of filename changes, because if you leave filename
unchanged and use the "OK" button to exit the dialog then this appears to be
indistinguishable from using the "Cancel" button.
I can't find anything in the documentation about how to do this. I tried to
use the {fstart,f,fend} functionality of Dynamic, but this caused
FileNameSetter to break.
