Slider controls

The Slider-Control widget is a virtual knob-and-track device with integrated numeric readout. Moving the knob along the track sets the associated INTEGER value to a proportional value within the range you have defined on the track. Conversely, setting the value of the associated variable moves the knob to the corresponding position along the track, offering the user a degree of analog, at-a-glance information that the number displayed by the readout does not.
