Struct gtk4::OverlayLayout

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

OverlayLayout is the layout manager used by Overlay.

It places widgets as overlays on top of the main child.

This is not a reusable layout manager, since it expects its widget to be a Overlay. It is only listed here so that its layout properties get documented.

Implements

LayoutManagerExt, glib::ObjectExt

Implementations

impl OverlayLayout

pub fn new() -> OverlayLayout

Creates a new OverlayLayout instance.

Returns

the newly created instance

Trait Implementations

impl Clone for OverlayLayout

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OverlayLayout

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

Formats the value using the given formatter.

impl Default for OverlayLayout

fn default() -> Self

Returns the “default value” for a type.

impl Display for OverlayLayout

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

Formats the value using the given formatter.

impl HasParamSpec for OverlayLayout

type ParamSpec = ParamSpecObject

type SetValue = OverlayLayout

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for OverlayLayout

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

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 OverlayLayout

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.

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 ParentClassIs for OverlayLayout

type Parent = LayoutManager

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

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 OverlayLayout

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.

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 OverlayLayout

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for OverlayLayout

impl IsA<LayoutManager> for OverlayLayout
