Class Details¶

class Gtk.Switch(**kwargs)¶

Bases:: Gtk.Widget, Gtk.Actionable
Abstract:: No

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

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

See [signal`Gtk`.Switch::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 [enum`Gtk`.AccessibleRole.switch] role.

classmethod new()[source]¶

Returns:: the newly created GtkSwitch instance
Return type:: Gtk.Widget

Creates a new GtkSwitch widget.

get_active()[source]¶

Returns:: True if the GtkSwitch is active, and False otherwise
Return type:: bool

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

get_state()[source]¶

Returns:: the underlying state
Return type:: bool

Gets the underlying state of the GtkSwitch.

set_active(is_active)[source]¶

Parameters:: is_active (bool) – True if self should be active, and False otherwise

Changes the state of self to the desired one.

set_state(state)[source]¶

Parameters:: state (bool) – the new state

Sets the underlying state of the GtkSwitch.

This function is typically called from a [signal`Gtk`.Switch::state-set] signal handler in order to set up delayed state changes.

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

Signal Details¶

Gtk.Switch.signals.activate(switch)¶

Signal Name:: activate
Flags:: RUN_FIRST, ACTION
Parameters:: switch (Gtk.Switch) – The object which received the signal

Emitted to animate the switch.

Applications should never connect to this signal, but use the [property`Gtk`.Switch:active] property.

Gtk.Switch.signals.state_set(switch, state)¶

Signal Name:

state-set

Flags:

RUN_LAST

Parameters:

switch (Gtk.Switch) – The object which received the signal
state (bool) – the new state of the switch

Returns:

True to stop the signal emission

Return type:

bool

Emitted to change the underlying state.

The ::state-set signal is emitted when the user changes the switch position. The default handler calls [method`Gtk`.Switch.set_state] with the value of state.

To implement delayed state change, applications can connect to this signal, initiate the change of the underlying state, and call [method`Gtk`.Switch.set_state] when the underlying state change is complete. The signal handler should return True to prevent the default handler from running.

Property Details¶

Gtk.Switch.props.active¶

Name:: active
Type:: bool
Default Value:: False
Flags:: READABLE, WRITABLE, EXPLICIT_NOTIFY

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

Gtk.Switch.props.state¶

Name:: state
Type:: bool
Default Value:: False
Flags:: READABLE, WRITABLE, EXPLICIT_NOTIFY

The backend state that is controlled by the switch.

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

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