Struct gtk4::BuilderScope

pub struct BuilderScope { /* private fields */ }

BuilderScope is an interface to provide language binding support to Builder.

The goal of BuilderScope is to look up programming-language-specific values for strings that are given in a Builder UI file.

The primary intended audience is bindings that want to provide deeper integration of Builder into the language.

A BuilderScope instance may be used with multiple Builder objects, even at once.

By default, GTK will use its own implementation of BuilderScope for the C language which can be created via Gtk::BuilderCScope::new().

If you implement BuilderScope for a language binding, you may want to (partially) derive from or fall back to a Gtk::BuilderCScope, as that class implements support for automatic lookups from C symbols.

pub const NONE: Option<&'static BuilderScope> = None

Trait Implementations

impl Clone for BuilderScope

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 BuilderScope

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

Formats the value using the given formatter.

impl HasParamSpec for BuilderScope

type ParamSpec = ParamSpecObject

type SetValue = BuilderScope

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for BuilderScope

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<T: BuilderScopeImpl> IsImplementable<T> for BuilderScope

fn interface_init(iface: &mut Interface<Self>)

Override the virtual methods of this interface for the given subclass and do other interface initialization.

fn instance_init(_instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for BuilderScope

fn cmp(&self, other: &Self) -> 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<OT: ObjectType> PartialEq<OT> for BuilderScope

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 BuilderScope

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 BuilderScope

fn static_type() -> Type

Returns the type identifier of Self.
