[java-dev] Open Dialog is worthless

Hey Matthew --

I ran into the same difficulty, but then I noticed that various  
filedialogs are included as part of the MaxSystem class (maybe the  
Runnable() scoping is why).

This code sets up a [loadbuf] message, with or without an additional  
filename as part of the message.  It reads the file into an internal  
buffer "lispbuf":

    String lispfname;

    public void loadbuf(String lf) {
       if (lf.length() == 0)
          lispfname = MaxSystem.openDialog();
       else lispfname = lf;

       if (lispfname != null) {
          try {
             File ff = new File(lispfname);
             FileReader fr = new FileReader(ff);
             char [] cbuf = new char[(int)ff.length()];
             fr.read(cbuf);
             lispbuf = new String(cbuf);
          } catch (IOException o) {
             error("could not load file: " + lispfname);
          }
       }
    }

hope this helps!
