Class

GtkSwitch

Description [src] 

final class Gtk.Switch : Gtk.Widget
  implements Gtk.Accessible, Gtk.Actionable, Gtk.Buildable, Gtk.ConstraintTarget {
  /* No available fields */
}

GtkSwitch is a “light switch” that has two states: on or off.

An example GtkSwitch

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

GtkSwitch can also express situations where the underlying state changes with a delay. In this case, the slider position indicates the user’s recent change (represented by the GtkSwitch:active property), while the trough color indicates the present underlying state (represented by the GtkSwitch:state property).

GtkSwitch with delayed state change

See GtkSwitch::state-set for details.

Shortcuts and Gestures

GtkSwitch supports pan and drag gestures to move the slider.

CSS nodes

switch
├── image
├── image
╰── slider

GtkSwitch has four css nodes, the main node with the name switch and subnodes for the slider and the on and off images. Neither of them is using any style classes.

Accessibility

GtkSwitch uses the GTK_ACCESSIBLE_ROLE_SWITCH role.
