Enum gtk4::ScrollStep

#[non_exhaustive]
pub enum ScrollStep {
    Steps,
    Pages,
    Ends,
    HorizontalSteps,
    HorizontalPages,
    HorizontalEnds,
}

Passed as argument to various keybinding signals.

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.

Steps

Scroll in steps.

Pages

Scroll by pages.

Ends

Scroll to ends.

HorizontalSteps

Scroll in horizontal steps.

HorizontalPages

Scroll by horizontal pages.

HorizontalEnds

Scroll to the horizontal ends.

Trait Implementations

fn clone(&self) -> ScrollStep

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollStep

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

Formats the value using the given formatter.

impl From<ScrollStep> for Value

fn from(v: ScrollStep) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for ScrollStep

type Checker = GenericValueTypeChecker<ScrollStep>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for ScrollStep

type ParamSpec = ParamSpecEnum

type SetValue = ScrollStep

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ScrollStep

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 ScrollStep

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

fn eq(&self, other: &ScrollStep) -> 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 PartialOrd for ScrollStep

fn partial_cmp(&self, other: &ScrollStep) -> 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 ScrollStep

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for ScrollStep

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for ScrollStep

type Type = ScrollStep

Type to get the Type from.

impl Copy for ScrollStep

impl Eq for ScrollStep

impl StructuralPartialEq for ScrollStep
