Struct gtk4::CenterLayout

#[repr(transparent)]
pub struct CenterLayout { /* private fields */ }

CenterLayout is a layout manager that manages up to three children.

The start widget is allocated at the start of the layout (left in left-to-right locales and right in right-to-left ones), and the end widget at the end.

The center widget is centered regarding the full width of the layout’s.

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

Performs copy-assignment from source.

impl Debug for CenterLayout

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

Formats the value using the given formatter.

impl Default for CenterLayout

fn default() -> Self

Returns the “default value” for a type.

impl Display for CenterLayout

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

Formats the value using the given formatter.

impl HasParamSpec for CenterLayout

type ParamSpec = ParamSpecObject

type SetValue = CenterLayout

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 CenterLayout

fn cmp(&self, other: &Self) -> 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.

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 ParentClassIs for CenterLayout

type Parent = LayoutManager

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

fn eq(&self, other: &OT) -> 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<OT: ObjectType> PartialOrd<OT> for CenterLayout

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

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 CenterLayout

fn static_type() -> Type

Returns the type identifier of Self.
