type ParentTypes GLTexture

Defined in GI.Gdk.Objects.GLTexture

type ParentTypes GLTexture = '[Texture, Object, Paintable, Icon, LoadableIcon]

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

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

Instances

(GObject o, IsDescendantOf GLTexture o) => IsGLTexture o

Defined in GI.Gdk.Objects.GLTexture

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

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

new

gLTextureNew

Arguments

:: (HasCallStack, MonadIO m, IsGLContext a)

=> a

context: a GdkGLContext

-> 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 GdkTexture

Deprecated: (Since version 4.12)GLTextureBuilder supersedes this functionand provides extended functionality for creating GL textures.

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

Arguments

:: (HasCallStack, MonadIO m, IsGLTexture a)

=> a

self: a GdkTexture wrapping a GL texture

-> m ()

Releases the GL resources held by a GdkGLTexture.

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