[flexcomponents] Manipulate Styles at runtime

[Firdosh Tangri]

Hey all,
     I have a HSlider where I set the trackSkin to my custom Class


    trackSkin="{SliderTrack}"

     So i get the class at runtime using the getStyles Property

     var sdSkin:Class= Class(video_HSlider.getStyle("trackSkin"));


     but how do go about accessing the properties and methods of SkinClass
so for example I want to
     change its width maybe.

cheers :)
