Enum gdk4::Gravity

#[non_exhaustive]
pub enum Gravity {
    NorthWest,
    North,
    NorthEast,
    West,
    Center,
    East,
    SouthWest,
    South,

}

Defines the reference point of a surface and is used in PopupLayout.

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.

NorthWest

the reference point is at the top left corner.

North

the reference point is in the middle of the top edge.

NorthEast

the reference point is at the top right corner.

West

the reference point is at the middle of the left edge.

Center

the reference point is at the center of the surface.

East

the reference point is at the middle of the right edge.

SouthWest

the reference point is at the lower left corner.

South

the reference point is at the middle of the lower edge.

SouthEast

the reference point is at the lower right corner.

Static

the reference point is at the top left corner of the surface itself, ignoring window manager decorations.

Trait Implementations

impl Clone for Gravity

fn clone(&self) -> Gravity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Gravity

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

Formats the value using the given formatter.

impl From<Gravity> for Value

fn from(v: Gravity) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for Gravity

type Checker = GenericValueTypeChecker<Gravity>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for Gravity

type ParamSpec = ParamSpecEnum

type SetValue = Gravity

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Gravity

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 Gravity

fn cmp(&self, other: &Gravity) -> 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 Gravity

fn eq(&self, other: &Gravity) -> 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 Gravity

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for Gravity

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 Gravity

type Type = Gravity

Type to get the Type from.

impl Copy for Gravity

impl Eq for Gravity

impl StructuralPartialEq for Gravity
