Struct GLTexture

pub struct GLTexture { /* private fields */ }

A GdkTexture representing a GL texture object.

Implements

TextureExt, PaintableExt, gio::prelude::IconExt, gio::prelude::LoadableIconExt, TextureExtManual

GLib type: GObject with reference counted clone semantics.

Implementations

impl GLTexture

pub fn release(&self)

Releases the GL resources held by a GLTexture.

The texture contents are still available via the TextureExtManual::download() function, after this function has been called.

impl GLTexture

pub unsafe fn new(context: &GLContext, id: u32, width: i32, height: i32) -> Self

Creates a new texture for an existing GL texture.

Note that the GL texture must not be modified until @destroy is called, which will happen when the GdkTexture object is finalized, or due to an explicit call of release().

Deprecated since 4.12

GLTextureBuilder supersedes this function and provides extended functionality for creating GL textures.

context

a GLContext

id

the ID of a texture that was created with @context

width

the nominal width of the texture

height

the nominal height of the texture

Returns

A newly-created Texture

pub unsafe fn with_release_func<F: FnOnce() + 'static>( context: &GLContext, id: u32, width: i32, height: i32, release_func: F, ) -> Self

pub fn builder() -> GLTextureBuilder

Available on crate feature v4_12 only.

Creates a new builder-pattern struct instance to construct GLTexture objects.

This method returns an instance of GLTextureBuilder which can be used to create GLTexture objects.

Trait Implementations

impl Clone for GLTexture

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 GLTexture

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

Formats the value using the given formatter.

impl HasParamSpec for GLTexture

type ParamSpec = ParamSpecObject

type SetValue = GLTexture

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GLTexture

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 GLTexture

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,

Restrict a value to a certain interval.

impl ParentClassIs for GLTexture

type Parent = Texture

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for GLTexture

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

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for GLTexture

fn static_type() -> Type

Returns the type identifier of Self.
