Slider Control

Hey,

Does anybody know of a working implementation of a slider widget?

I find this documentation: http://www.cocos2d-x.org/embedded/cocos2d-x/d1/d6f/classcocos2d_1_1extension_1_1_c_c_control_slider.html
The CCControlExtension.zip found under Extensions does not compile because of missing CCScale9Sprite.h.

Regards,
Nathan
