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.

Properties

shrink-center-last

Whether to shrink the center widget after other children.

By default, when there’s no space to give all three children their natural widths, the start and end widgets start shrinking and the center child keeps natural width until they reach minimum width.

If set to FALSE, start and end widgets keep natural width and the center widget starts shrinking instead.

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

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for 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.

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.

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.
