# Spinner (lv_spinner)
|
|
|
|
## Overview
|
|
The Spinner object is a spinning arc over a ring.
|
|
|
|
## Parts and Styles
|
|
The parts are identical to the parts of [lv_arc](/widgets/core/arc).
|
|
|
|
## Usage
|
|
|
|
### Create a spinner
|
|
|
|
To create a spinner use `lv_spinner_create(parent, spin_time, arc_length)`. `spin time` sets the spin time in milliseconds, `arc_length` sets the length of the spinning arc in degrees.
|
|
|
|
## Events
|
|
No special events are sent to the Spinner.
|
|
|
|
See the events of the [Arc](/widgets/core/arc) too.
