- List of all members, including inherited members

## Properties

- activeFocusOnPress : bool
- hovered : real
- maximumValue : real
- minimumValue : real
- pressed : bool
- stepSize : real
- tickmarksVisible : bool
- value : real

## Detailed Description

The Dial is similar to a traditional dial knob that is found on devices such as stereos or industrial equipment. It allows the user to specify a value within a range.

Like CircularGauge, Dial can display tickmarks to give an indication of the current value. When a suitable stepSize is combined with tickmarkStepSize, the dial "snaps" to each tickmark.

You can create a custom appearance for a Dial by assigning a DialStyle.
