Constructor Detail

def self.new(context : Gdk::GLContext, id : UInt32, width : Int32, height : Int32, destroy : GLib::DestroyNotify, data : Pointer(Void) | Nil) : 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 Gdk::Texture object is finalized, or due to an explicit call of Gdk::GLTexture#release.

def self.new #

Initialize a new GLTexture.

def self.new(*, height : Int32 | Nil = nil, width : Int32 | Nil = nil) #

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def release : Nil #

Releases the GL resources held by a Gdk::GLTexture.

The texture contents are still available via the Gdk::Texture#download function, after this function has been called.
