Struct pango::FontMap

pub struct FontMap { /* private fields */ }

A FontMap represents the set of fonts available for a particular rendering system.

This is a virtual object with implementations being specific to particular rendering systems.

This is an Abstract Base Class, you cannot instantiate it.

Properties

item-type

The type of items contained in this list.

Readable

n-items

The number of items contained in this list.

Readable

Implements

FontMapExt, gio::prelude::ListModelExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl FontMap

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

Trait Implementations

impl Clone for FontMap

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for FontMap

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

Formats the value using the given formatter.

impl HasParamSpec for FontMap

type ParamSpec = ParamSpecObject

type SetValue = FontMap

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FontMap

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

where H: Hasher,

Hashes the memory address of this object.

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 FontMap

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 ParentClassIs for FontMap

type Parent = Object

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

fn eq(&self, other: &OT) -> bool

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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 FontMap

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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 FontMap

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for FontMap
