Enum gtk4::ScrollablePolicy

#[non_exhaustive]
pub enum ScrollablePolicy {
    Minimum,
    Natural,
}

Defines the policy to be used in a scrollable widget when updating the scrolled window adjustments in a given orientation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Minimum

Scrollable adjustments are based on the minimum size

Natural

Scrollable adjustments are based on the natural size

impl From<ScrollablePolicy> for Value

fn from(v: ScrollablePolicy) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for ScrollablePolicy

type Checker = GenericValueTypeChecker<ScrollablePolicy>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for ScrollablePolicy

type ParamSpec = ParamSpecEnum

type SetValue = ScrollablePolicy

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

type BuilderFn = fn(_: &str, _: ScrollablePolicy) -> ParamSpecEnumBuilder<'_, ScrollablePolicy>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ScrollablePolicy

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

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 ScrollablePolicy

fn cmp(&self, other: &ScrollablePolicy) -> 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 PartialEq<ScrollablePolicy> for ScrollablePolicy

fn eq(&self, other: &ScrollablePolicy) -> 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.

fn partial_cmp(&self, other: &ScrollablePolicy) -> 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.

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 ScrollablePolicy

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for ScrollablePolicy

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for ScrollablePolicy

type Type = ScrollablePolicy

Type to get the Type from.
