public abstract C getSkinnable ()

Gets the Skinnable to which this Skin is assigned. A Skin must be created for one and only one Skinnable. This value will only ever go from a non-null to null value when the Skin is removed from the Skinnable, and only as a consequence of a call to dispose().

The caller who constructs a Skinnable must also construct a Skin and properly establish the relationship between the Control and its Skin.

Returns:  A non-null Skinnable, or null value if disposed.
