| # 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.
 | |
| 
 | |
| Learn more about [Events](/overview/event).
 | |
| 
 | |
| ## Keys
 | |
| No *Keys* are processed by the object type.
