Description

Switch is a widget 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 handle.

GtkSwitch can also handle situations where the underlying state changes with a delay. See Switch::state-set for details.

CSS nodes

plain code

switch
╰── slider

GtkSwitch has two css nodes, the main node with the name switch and a subnode named slider. Neither of them is using any style classes.

toSwitch :: (MonadIO m, IsSwitch o) => o -> m Switch Source #

Cast to Switch, for types for which this is known to be safe. For general casts, use castTo.

noSwitch :: Maybe Switch Source #

A convenience alias for Nothing :: Maybe Switch.

Methods

getActive

switchGetActive Source #

Arguments

:: (HasCallStack, MonadIO m, IsSwitch a)
=> a	`sw`: a `Switch`
-> m Bool	Returns: `True` if the `Switch` is active, and `False` otherwise

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

Since: 3.0

getState

switchGetState Source #

Arguments

:: (HasCallStack, MonadIO m, IsSwitch a)
=> a	`sw`: a `Switch`
-> m Bool	Returns: the underlying state

Gets the underlying state of the Switch.

Since: 3.14

new

switchNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> m Switch	Returns: the newly created `Switch` instance

Creates a new Switch widget.

Since: 3.0

setActive

switchSetActive Source #

Arguments

:: (HasCallStack, MonadIO m, IsSwitch a)
=> a	`sw`: a `Switch`
-> Bool	`isActive`: `True` if `sw` should be active, and `False` otherwise
-> m ()

Changes the state of sw to the desired one.

Since: 3.0

setState

switchSetState Source #

Arguments

:: (HasCallStack, MonadIO m, IsSwitch a)
=> a	`sw`: a `Switch`
-> Bool	`state`: the new state
-> m ()

Sets the underlying state of the Switch.

Normally, this is the same as Switch:active, unless the switch is set up for delayed state changes. This function is typically called from a Switch::state-set signal handler.

See Switch::state-set for details.

Since: 3.14

Properties

active

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

constructSwitchActive :: IsSwitch o => Bool -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “active” property. This is rarely needed directly, but it is used by new.

getSwitchActive :: (MonadIO m, IsSwitch o) => o -> m Bool Source #

Get the value of the “active” property. When overloading is enabled, this is equivalent to

get switch #active

setSwitchActive :: (MonadIO m, IsSwitch o) => o -> Bool -> m () Source #

Set the value of the “active” property. When overloading is enabled, this is equivalent to

set switch [ #active := value ]

state

The backend state that is controlled by the switch. See Switch::state-set for details.

Since: 3.14

constructSwitchState :: IsSwitch o => Bool -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “state” property. This is rarely needed directly, but it is used by new.

getSwitchState :: (MonadIO m, IsSwitch o) => o -> m Bool Source #

Get the value of the “state” property. When overloading is enabled, this is equivalent to

get switch #state

setSwitchState :: (MonadIO m, IsSwitch o) => o -> Bool -> m () Source #

Set the value of the “state” property. When overloading is enabled, this is equivalent to

set switch [ #state := value ]

Signals

activate

type C_SwitchActivateCallback = Ptr () -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type SwitchActivateCallback = IO () Source #

The ::activate signal on GtkSwitch is an action signal and emitting it causes the switch to animate. Applications should never connect to this signal, but use the notify::active signal.

afterSwitchActivate :: (IsSwitch a, MonadIO m) => a -> SwitchActivateCallback -> m SignalHandlerId Source #

Connect a signal handler for the “activate” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after switch #activate callback

genClosure_SwitchActivate :: SwitchActivateCallback -> IO Closure Source #

Wrap the callback into a Closure.

mk_SwitchActivateCallback :: C_SwitchActivateCallback -> IO (FunPtr C_SwitchActivateCallback) Source #

Generate a function pointer callable from C code, from a C_SwitchActivateCallback.

noSwitchActivateCallback :: Maybe SwitchActivateCallback Source #

A convenience synonym for Nothing :: Maybe SwitchActivateCallback.

onSwitchActivate :: (IsSwitch a, MonadIO m) => a -> SwitchActivateCallback -> m SignalHandlerId Source #

Connect a signal handler for the “activate” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on switch #activate callback

wrap_SwitchActivateCallback :: SwitchActivateCallback -> C_SwitchActivateCallback Source #

Wrap a SwitchActivateCallback into a C_SwitchActivateCallback.

stateSet

type C_SwitchStateSetCallback = Ptr () -> CInt -> Ptr () -> IO CInt Source #

Type for the callback on the (unwrapped) C side.

type SwitchStateSetCallback Source #

Arguments

= Bool	`state`: the new state of the switch
-> IO Bool	Returns: `True` to stop the signal emission

The ::state-set signal on GtkSwitch is emitted to change the underlying state. It is emitted when the user changes the switch position. The default handler keeps the state in sync with the Switch:active property.

To implement delayed state change, applications can connect to this signal, initiate the change of the underlying state, and call switchSetState when the underlying state change is complete. The signal handler should return True to prevent the default handler from running.

Visually, the underlying state is represented by the trough color of the switch, while the Switch:active property is represented by the position of the switch.

Since: 3.14

afterSwitchStateSet :: (IsSwitch a, MonadIO m) => a -> SwitchStateSetCallback -> m SignalHandlerId Source #

Connect a signal handler for the “state-set” signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after switch #stateSet callback

genClosure_SwitchStateSet :: SwitchStateSetCallback -> IO Closure Source #

Wrap the callback into a Closure.

mk_SwitchStateSetCallback :: C_SwitchStateSetCallback -> IO (FunPtr C_SwitchStateSetCallback) Source #

Generate a function pointer callable from C code, from a C_SwitchStateSetCallback.

noSwitchStateSetCallback :: Maybe SwitchStateSetCallback Source #

A convenience synonym for Nothing :: Maybe SwitchStateSetCallback.

onSwitchStateSet :: (IsSwitch a, MonadIO m) => a -> SwitchStateSetCallback -> m SignalHandlerId Source #

Connect a signal handler for the “state-set” signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on switch #stateSet callback

wrap_SwitchStateSetCallback :: SwitchStateSetCallback -> C_SwitchStateSetCallback Source #

Wrap a SwitchStateSetCallback into a C_SwitchStateSetCallback.
