Overview

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 [propertyGtk.Switch:active] property), while the trough color indicates the present underlying state (represented by the [propertyGtk.Switch:state] property).

GtkSwitch with delayed state change

See [signalGtk.Switch::state-set] for details.

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.

Constructor Details

#initialize ⇒ Gtk::Widget

Creates a new GtkSwitch widget.

Instance Method Details

#active ⇒ Boolean

Gets whether the GtkSwitch is in its “on” or “off” state.

Returns:

  • (Boolean) —

    true if the GtkSwitch is active, and false otherwise

#active=(active) ⇒ Boolean

Whether the GtkSwitch widget is in its on or off state.

Parameters:

  • active (Boolean)

Returns:

  • (Boolean) —

    active

  • (Boolean) —

    active

#active? ⇒ Boolean

Whether the GtkSwitch widget is in its on or off state.

Returns:

  • (Boolean) —

    active

#state ⇒ Boolean

Gets the underlying state of the GtkSwitch.

Returns:

  • (Boolean) —

    the underlying state

#state=(state) ⇒ Boolean

The backend state that is controlled by the switch.

Applications should usually set the [propertyGtk.Switch:active] property, except when indicating a change to the backend state which occurs separately from the user's interaction.

See [signalGtk.Switch::state-set] for details.

Parameters:

  • state (Boolean)

Returns:

  • (Boolean) —

    state

  • (Boolean) —

    state

#state? ⇒ Boolean

The backend state that is controlled by the switch.

Applications should usually set the [propertyGtk.Switch:active] property, except when indicating a change to the backend state which occurs separately from the user's interaction.

See [signalGtk.Switch::state-set] for details.

Returns:

  • (Boolean) —

    state
