Struct SignalGroup

pub struct SignalGroup { /* private fields */ }

Available on crate feature v2_74 only.

GLib type: GObject with reference counted clone semantics.

Implementations

impl SignalGroup

pub fn with_type(target_type: Type) -> SignalGroup

pub fn block(&self)

pub fn target(&self) -> Option<Object>

pub fn set_target(&self, target: Option<&impl IsA<Object>>)

pub fn unblock(&self)

pub fn target_type(&self) -> Type

Available on crate feature v2_72 only.

impl SignalGroup

pub fn new<T: IsA<Object>>() -> Self

pub fn connect_closure( &self, signal_name: &str, after: bool, closure: RustClosure, )

pub fn connect<F>(&self, signal_name: &str, after: bool, callback: F)

where F: Fn(&[Value]) -> Option<Value> + Send + Sync + 'static,

pub fn connect_local<F>(&self, signal_name: &str, after: bool, callback: F)

where F: Fn(&[Value]) -> Option<Value> + 'static,

Like Self::connect but doesn’t require a Send+Sync closure. Signal emission will panic if the signal on the current target is emitted from a different thread from the thread that connected the signal.

pub fn connect_notify<F>(&self, name: Option<&str>, callback: F)

where F: Fn(&Object, &ParamSpec) + Send + Sync + 'static,

pub fn connect_notify_local<F>(&self, name: Option<&str>, callback: F)

where F: Fn(&Object, &ParamSpec) + 'static,

pub fn connect_bind<F: Fn(&Self, &Object) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_bind_local<F: Fn(&Self, &Object) + 'static>( &self, f: F, ) -> SignalHandlerId

Like Self::connect_bind but doesn’t require a Send+Sync closure. Signal emission will panic if the signal is emitted from a different thread from the thread that connected the signal.

pub fn connect_unbind<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

pub fn connect_unbind_local<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Like Self::connect_unbind but doesn’t require a Send+Sync closure. Signal emission will panic if the signal is emitted from a different thread from the thread that connected the signal.

Trait Implementations

impl Clone for SignalGroup

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for SignalGroup

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

Formats the value using the given formatter.

impl HasParamSpec for SignalGroup

type ParamSpec = ParamSpecObject

type SetValue = SignalGroup

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SignalGroup

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

where H: Hasher,

Hashes the memory address of this object.

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 SignalGroup

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for SignalGroup

type Parent = Object

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

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

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

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for SignalGroup

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for SignalGroup

impl Send for SignalGroup

impl Sync for SignalGroup
