Used by These Methods / Signals / Properties

Class / Namespace	Method / Signal / Properties
Cogl Method	Cogl.clear (Color color, Number buffers) : none Clears all the auxiliary buffers identified in the buffers mask, and if that includes the color buffer then the specified color is used.
Cogl Method	Cogl.material_get_ambient (void* material, Color ambient) : none Retrieves the current ambient color for material
Cogl Method	Cogl.material_get_color (void* material) : Cogl.Color Retrieves the current material color.
Cogl Method	Cogl.material_get_diffuse (void* material, Color diffuse) : none Retrieves the current diffuse color for material
