Struct gdk4::GLTexture

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

A GdkTexture representing a GL texture object.

Implements

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

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().

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

Trait Implementations

impl Clone for GLTexture

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 GLTexture

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

Formats the value using the given formatter.

impl Display for GLTexture

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

Formats the value using the given formatter.

impl Hash for GLTexture

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 GLTexture

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 GLTexture

type Parent = Texture

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

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 GLTexture

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 GLTexture

fn static_type() -> Type

Returns the type identifier of Self.
