I just had a go at this but unfortunately it uses a C++ library to do
the actual dialog creation. Various lines like:

#this is where the open & save stuff happens
     if {$boxflag == "open"} {
          set filename $entry
         # A file is being opened, so we call the c++ function to open a 
file.
         # We call function cppOpenCD in the iGraph object, passing it 
the file
         set retVal [$iGraph cppOpenCD: $entry]
...

So the cppOpenCD call in the iGraph library is the key to whatever
is going on here. Busted again... :-(
