Methods / Constructors
Method / Constructor		Defined By
	new Clutter.Shader (Object *properties) Create a new Clutter.Shader Create a new Clutter.Shader Parameters: Object properties*
	compile () : gboolean Compiles and links GLSL sources set for vertex and fragment shaders for a ClutterShader. Compiles and links GLSL sources set for vertex and fragment shaders for a ClutterShader. If the compilation fails and a GError return location is provided the error will contain the errors from the compiler, if any. Returns: gboolean returns TRUE if the shader was succesfully compiled.	Clutter.Shader
	get_cogl_fragment_shader () : void* Retrieves the underlying CoglHandle for the fragment shader. Retrieves the underlying CoglHandle for the fragment shader. Returns: void* A CoglHandle for the fragment shader, or NULL	Clutter.Shader
	get_cogl_program () : void* Retrieves the underlying CoglHandle for the shader program. Retrieves the underlying CoglHandle for the shader program. Returns: void* A CoglHandle for the shader program, or NULL	Clutter.Shader
	get_cogl_vertex_shader () : void* Retrieves the underlying CoglHandle for the vertex shader. Retrieves the underlying CoglHandle for the vertex shader. Returns: void* A CoglHandle for the vertex shader, or NULL	Clutter.Shader
	get_fragment_source () : String Query the current GLSL fragment source set on shader. Query the current GLSL fragment source set on shader. ClutterShader object or NULL. The returned string is owned by the shader object and should never be modified or freed Returns: String the source of the fragment shader for this	Clutter.Shader
	get_is_enabled () : gboolean Checks whether shader is enabled. Checks whether shader is enabled. Returns: gboolean TRUE if the shader is enabled.	Clutter.Shader
	get_vertex_source () : String Query the current GLSL vertex source set on shader. Query the current GLSL vertex source set on shader. ClutterShader object or NULL. The returned string is owned by the shader object and should never be modified or freed Returns: String the source of the vertex shader for this	Clutter.Shader
	is_compiled () : gboolean Checks whether shader is is currently compiled, linked and bound to the GL context. Checks whether shader is is currently compiled, linked and bound to the GL context. Returns: gboolean TRUE if the shader is compiled, linked and ready for use.	Clutter.Shader
	release () : none Frees up any GL context resources held by the shader. Frees up any GL context resources held by the shader. Returns: none	Clutter.Shader
	set_fragment_source (String *data, gint32 length) : none Sets the GLSL source code to be used by a ClutterShader* for the fragment program. Sets the GLSL source code to be used by a ClutterShader for the fragment program. Parameters: String data Required (not null) GLSL source code. gint32 length Required (not null) length of source buffer (currently ignored) Returns: none	Clutter.Shader
	set_is_enabled (gboolean *enabled) : none Enables a shader. Enables a shader. This function will attempt to compile and link the shader, if it isn't already. When enabled* is FALSE the default state of the GL pipeline will be used instead. Parameters: gboolean enabled Required (not null) The new state of the shader. Returns: none	Clutter.Shader
	set_uniform (String *name, Value value) : none Sets a user configurable variable in the GLSL shader programs attached to a ClutterShader. Sets a user configurable variable in the GLSL shader programs attached to a ClutterShader. Parameters: String name* Required (not null) name of uniform in GLSL shader program to set. GObject.Value value Required (not null) a ClutterShaderFloat, ClutterShaderInt or ClutterShaderMatrix GValue. Returns: none	Clutter.Shader
	set_vertex_source (String *data, gint32 length) : none Sets the GLSL source code to be used by a ClutterShader* for the vertex program. Sets the GLSL source code to be used by a ClutterShader for the vertex program. Parameters: String data Required (not null) GLSL source code. gint32 length Required (not null) length of source buffer (currently ignored) Returns: none	Clutter.Shader
