Struct gtk4::SignalAction

#[repr(transparent)]
pub struct SignalAction { /* private fields */ }

A ShortcutAction that emits a signal.

Signals that are used in this way are referred to as keybinding signals, and they are expected to be defined with the G_SIGNAL_ACTION flag.

Properties

signal-name

The name of the signal to emit.

Readable | Writeable | Construct Only

Implements

ShortcutActionExt, glib::ObjectExt

Implementations

impl SignalAction

pub fn new(signal_name: &str) -> SignalAction

Creates an action that when activated, emits the given action signal on the provided widget.

It will also unpack the args into arguments passed to the signal.

signal_name

name of the signal to emit

Returns

a new ShortcutAction

pub fn signal_name(&self) -> GString

Returns the name of the signal that will be emitted.

Returns

the name of the signal to emit

Trait Implementations

impl Clone for SignalAction

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignalAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SignalAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for SignalAction

type ParamSpec = ParamSpecObject

type SetValue = SignalAction

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, SignalAction>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SignalAction

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SignalAction

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for SignalAction

type Parent = ShortcutAction

impl<OT: ObjectType> PartialEq<OT> for SignalAction

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for SignalAction

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for SignalAction

fn static_type() -> Type

Returns the type identifier of Self.
