###Props

####afterSlide React.PropTypes.func

Hook to be called after a slide is changed.

####autoplay React.PropTypes.bool

Autoplay mode active. Defaults to false.

####autoplayInterval React.PropTypes.number

Interval for autoplay iteration. Defaults to 3000.

####beforeSlide React.PropTypes.func

Hook to be called before a slide is changed.

####cellAlign React.PropTypes.oneOf(['left', 'center', 'right'])

####cellSpacing React.PropTypes.number

####data React.PropTypes.func

Used with the ControllerMixin to add carousel data to parent state.

####decorators React.PropTypes.array

An array of objects that supply internal carousel controls. Decorator objects have component, position & style properties. component takes a React component, position takes a predefined position string and style takes an object of styles to be applied to the decorator. See an example below:

var Decorators = [{
  component: React.createClass({
    render() {
      return (
        <button
          onClick={this.props.previousSlide}>
          Previous Slide
        </button>
      )
    }
  }),
  position: 'CenterLeft',
  style: {
  	padding: 20
  }
}];

// Valid position properties are TopLeft, TopCenter, TopRight
// CenterLeft, CenterCenter, CenterRight, BottomLeft, BottomCenter
// and BottomRight

####dragging React.PropTypes.bool

Enable mouse swipe/dragging

####easing React.PropTypes.string

Animation easing function. See valid easings here: https://github.com/chenglou/tween-functions

####fixedHeight React.PropTypes.bool

If set to true will set the height of the frame to the tallest slide in the carousel. If set to false, will set the height of the frame to the height of the current slide. Default value is true`.

Note: If slidesToShow > 1 the height of the frame may clip other shown slides if their height are greater than the current slide.

####framePadding React.PropTypes.string

####initialSlideWidth React.PropTypes.number

Initial width of the slides in pixels.

####scrollMode

scrollMode: React.PropTypes.oneOf([
  'page',
  'remainder'
])

Sets scroll limit of the carousel. 'page' will scroll until the last slide is in the props.cellAlign position, but is overridden by wrapAround. 'remainder' will scroll until the last slide is in the last slot established by slidesToShow.

####slideIndex React.PropTypes.number

Manually set the index of the slide to be shown.

####slidesToShow React.PropTypes.number

Slides to show at once.

####slidesToScroll

slidesToScroll: React.PropTypes.oneOfType([
  React.PropTypes.number,
  React.PropTypes.oneOf(['auto'])
])

Slides to scroll at once. Set to "auto" to always scroll the current number of visible slides.

####slideWidth

React.PropTypes.oneOfType([React.PropTypes.string, React.PropTypes.number])

Manually set slideWidth. If you want hard pixel widths, use a string like slideWidth="20px", and if you prefer a percentage of the container, use a decimal integer like slideWidth={0.8}

###ControllerMixin

The ControllerMixin provides a way to add external controllers for a carousel. To use the controller mixin, add it to your parent component as shown below:

const App = React.createClass({
  mixins: [Carousel.ControllerMixin],
  render() {
    return (
      <Carousel ref="carousel" data={this.setCarouselData.bind(this, 'carousel')}>
        ...
      </Carousel>
    )
  }
});

It is required to give your component a ref value, and to pass the setCarouselData method to the data prop with the same ref as an argument.

After setting this up, your parent component has a carousels object in it's state. You can now control your carousels from other child components:

const App = React.createClass({
  mixins: [Carousel.ControllerMixin],
  render() {
    return (
      <Carousel ref="carousel" data={this.setCarouselData.bind(this, 'carousel')}>
        ...
      </Carousel>
      {this.state.carousels.carousel ? <button type="button" onClick={this.state.carousels.carousel.goToSlide.bind(null,4)}>
        Go to slide 5
      </button> : null}
    )
  }
});
