Readable

Action

enabled

If action is currently enabled.

If the action is disabled then calls to [ActionExtManual::activate()][crate::gio::prelude::ActionExtManual::activate()] and [ActionExtManual::change_state()][crate::gio::prelude::ActionExtManual::change_state()] have no effect.

Readable

name

The name of the action. This is mostly meaningful for identifying the action once it has been added to a [gio::ActionGroup][crate::gio::ActionGroup]. It is immutable.

Readable

parameter-type

The type of the parameter that must be given when activating the action. This is immutable, and may be None if no parameter is needed when activating the action.

Readable

state

The state of the action, or None if the action is stateless.

Readable

state-type

The [glib::VariantType][crate::glib::VariantType] of the state that the action has, or None if the action is stateless. This is immutable.

Implementations

impl ChildPropertyAction

pub fn child(&self) -> Option<Widget>

pub fn child_property_name(&self) -> Option<GString>

pub fn container(&self) -> Option<Container>

pub fn new( name: &str, container: &impl IsA<Container>, child: &impl IsA<Widget>, child_property_name: &str ) -> Option<Action>

This creates a new [gio::Action][crate::gio::Action] that will change when the underlying child property of container changes for child.

name

the name of the action

container

the container of the widget

child

the widget for the child property

child_property_name

the name of the child property

Returns

A new ChildPropertyAction.

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

Trait Implementations

impl Clone for ChildPropertyAction

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 ChildPropertyAction

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

Formats the value using the given formatter.

impl Display for ChildPropertyAction

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

Formats the value using the given formatter.

impl HasParamSpec for ChildPropertyAction

type ParamSpec = ParamSpecObject

type SetValue = ChildPropertyAction

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ChildPropertyAction

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 ChildPropertyAction

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

This method returns an Ordering between self and other.

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 + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for ChildPropertyAction

type Parent = Object

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

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 ChildPropertyAction

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 ChildPropertyAction

fn static_type() -> Type

Returns the type identifier of Self.
