Introduction

This quick and small example shows how to use customised gauges on the front panel to create an analogue clock. The block diagram uses Invoke Methods to resize the gauges so that the size of the clock is automatically adjusted to fit to the size of the window. The system time is retrieved and parsed into hours, minutes, seconds, and milliseconds. The values are converted to single precision. Fractional values are added on from its lesser significant unit, and values are checked to see if they will display properly on the dial.
