Struct StyleContext 

pub struct StyleContext { /* private fields */ }

Implementations

impl StyleContext

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

pub fn new() -> StyleContext

pub fn builder() -> StyleContextBuilder

Creates a new builder-pattern struct instance to construct StyleContext objects.

This method returns an instance of StyleContextBuilder which can be used to create StyleContext objects.

pub fn add_provider_for_screen( screen: &Screen, provider: &impl IsA<StyleProvider>, priority: u32, )

pub fn remove_provider_for_screen( screen: &Screen, provider: &impl IsA<StyleProvider>, )

pub fn reset_widgets(screen: &Screen)

Trait Implementations

Performs copy-assignment from source.

impl Debug for StyleContext

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

Formats the value using the given formatter.

impl Default for StyleContext

fn default() -> Self

Returns the “default value” for a type.

impl Display for StyleContext

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for StyleContext

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 StyleContext

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,

Restrict a value to a certain interval.

impl ParentClassIs for StyleContext

type Parent = Object

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

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

Tests for self and other values to be equal, and is used by ==.

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 StyleContext

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

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 StyleContext

fn static_type() -> Type

Returns the type identifier of Self.
