id docs for UIComponent there is no such method. Horizontal and vertical exists.
rotatedGradientMatrix there is only for ProgrammaticSkin.
What version of SDK do you use?
Don't all those properties get inherited from programmatic skins?
UIComponent not a subclass of ProgrammaticSkin... so not.
Click Show Inherited Methods in docs and you will see all methods and properties. In ProgrammaticSkin this method is protected.
Yeah, i was thinking the other way around. I wonder why they would leave that out of UIComponent.
