Description:

[ CCode ( type_id = "gtk_switch_get_type ()" ) ]
public sealed class Switch : Widget, Accessible, Actionable, Buildable, ConstraintTarget

`GtkSwitch` is a "light switch" that has two states: on or off.

![An example GtkSwitch](switch.png)

The user can control which state should be active by clicking the empty area, or by dragging the handle.

`GtkSwitch` can also handle situations where the underlying state changes with a delay. In this case, the slider position indicates the user's recent change (as indicated by the [property@Gtk.Switch:active] property), and the color indicates whether the underlying state (represented by the [property@Gtk.Switch:state] property) has been updated yet.

See [signal@Gtk.Switch:GtkSwitch:state-set] for details.
