Description

Represents a general-purpose knob-style rotating button.

Use a TArcDial button in applications wherever you need to provide the user with a rotating button that resembles a knob. This arc dial control variates its Value in degrees, so if you want to use it as a linear control for varying the progress of a progress bar, for instance, you need to programmatically make a conversion from degrees to linear movement.

Control whether this arc dial component displays the value or not using the FMX.Controls.TArcDial.ShowValue property.
