Struct AccessibleRange 

pub struct AccessibleRange { /* private fields */ }

Available on crate feature v4_10 only.

An interface for accessible objects containing a numeric value.

AccessibleRange describes ranged controls for Assistive Technologies.

Ranged controls have a single value within an allowed range that can optionally be changed by the user.

This interface is expected to be implemented by controls using the following roles:

• GTK_ACCESSIBLE_ROLE_METER
• GTK_ACCESSIBLE_ROLE_PROGRESS_BAR
• GTK_ACCESSIBLE_ROLE_SCROLLBAR
• GTK_ACCESSIBLE_ROLE_SLIDER
• GTK_ACCESSIBLE_ROLE_SPIN_BUTTON

If that is not the case, a warning will be issued at run time.

In addition to this interface, its implementers are expected to provide the correct values for the following properties:

• GTK_ACCESSIBLE_PROPERTY_VALUE_MAX
• GTK_ACCESSIBLE_PROPERTY_VALUE_MIN
• GTK_ACCESSIBLE_PROPERTY_VALUE_NOW
• GTK_ACCESSIBLE_PROPERTY_VALUE_TEXT

GLib type: GObject with reference counted clone semantics.

Implementations

impl AccessibleRange

pub const NONE: Option<&'static AccessibleRange> = None

Trait Implementations

impl Clone for AccessibleRange

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 AccessibleRange

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

Formats the value using the given formatter.

impl HasParamSpec for AccessibleRange

type ParamSpec = ParamSpecObject

type SetValue = AccessibleRange

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for AccessibleRange

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<T: AccessibleRangeImpl> IsImplementable<T> for AccessibleRange

fn interface_init(iface: &mut Interface<Self>)

Override the virtual methods of this interface for the given subclass and do other interface initialization.

fn instance_init(_instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for AccessibleRange

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<OT: ObjectType> PartialEq<OT> for AccessibleRange

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 AccessibleRange

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 AccessibleRange

fn static_type() -> Type

Returns the type identifier of Self.
