Indeed. At the time that was written TK scale widgets only supported integer values, so I used integers in the 0-100 range for simplicity. It should really be floating point however. And TK scale widgets apparently support that now so in principle the TK support could be made compatible with the new format file. -- Maurice LeBrun ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
