class (GObject o, IsDescendantOf GLTexture o) => IsGLTexture o Source #

Type class for types which can be safely cast to GLTexture, for instance with toGLTexture.

toGLTexture :: (MonadIO m, IsGLTexture o) => o -> m GLTexture Source #

Cast to GLTexture, for types for which this is known to be safe. For general casts, use castTo.

noGLTexture :: Maybe GLTexture Source #

A convenience alias for Nothing :: Maybe GLTexture.

Methods

Overloaded methods

new

gLTextureNew Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLContext a)
=> a	`context`: a `GLContext`
-> Word32	`id`: the ID of a texture that was created with `context`
-> Int32	`width`: the nominal width of the texture
-> Int32	`height`: the nominal height of the texture
-> DestroyNotify	`destroy`: a destroy notify that will be called when the GL resources are released
-> Ptr ()	`data`: data that gets passed to `destroy`
-> m GLTexture	Returns: A newly-created `Texture`

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 gLTextureRelease.

release

gLTextureRelease Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTexture a)
=> a	`self`: a `Texture` wrapping a GL texture
-> m ()

Releases the GL resources held by a GLTexture that was created with gLTextureNew.

The texture contents are still available via the textureDownload function, after this function has been called.
