Hi Kjetil,
Thank you very much for the response. Yes you understand the problem
correctly. The numeric entry next to a QT slider display the correct number
of digits but truncates the number displayed to three decimal places.
I think you're theory is right, it certainly seems likely that the numeric
entries can support a higher precision than the sliders. I tired changing
the hardcoded range but it had no effect. I will settle for 3 decimal
places for now :).
Regards,
Aidan.
