## API

### createSliderWithTooltip(Slider | Range) => React.Component

An extension to make Slider or Range support Tooltip on handle.

```jsx
const Slider = require('rc-slider');
const createSliderWithTooltip = Slider.createSliderWithTooltip;
const Range = createSliderWithTooltip(Slider.Range);
```

[Online demo](http://react-component.github.io/slider/examples/handle.html)

After Range or Slider was wrapped by createSliderWithTooltip, it will have the following props:

| Name         | Type    | Default | Description |
| ------------ | ------- | ------- | ----------- |
| tipFormatter | (value: number): React.ReactNode | `value => value` | A function to format tooltip's overlay |
| tipProps | Object | `{` <br>`placement: 'top',` <br> ` prefixCls: 'rc-slider-tooltip',` <br> `overlay: tipFormatter(value)` <br> `}` | A function to format tooltip's overlay |

### Common API

The following APIs are shared by Slider and Range.

| Name         | Type    | Default | Description |
| ------------ | ------- | ------- | ----------- |
| className | string | `''` | Additional CSS class for the root DOM node |
| min | number | `0` | The minimum value of the slider |
| max | number | `100` | The maximum value of the slider |
| marks | `{number: string}` or`{number: { style, label }}` | `{}` | Marks on the slider. The key determines the position, and the value determines what will show. If you want to set the style of a specific mark point, the value should be an object which contains `style` and `label` properties. |
| step | number or `null` | `1` | Value to be added or subtracted on each step the slider makes. Must be greater than zero, and `max` - `min` should be evenly divisible by the step value. <br /> When `marks` is not an empty object, `step` can be set to `null`, to make `marks` as steps. |
| vertical | boolean | `false` | If vertical is `true`, the slider will be vertical. |
| handle | (props) => React.ReactNode | | A handle generator which could be used to customized handle. |
| included | boolean | `true` | If the value is `true`, it means a continuous value interval, otherwise, it is a independent value. |
| disabled | boolean | `false` | If `true`, handles can't be moved. |
| dots | boolean | `false` | When the `step` value is greater than 1, you can set the `dots` to  `true` if you want to render the slider with dots. |
| onBeforeChange | Function | NOOP | `onBeforeChange` will be triggered when `ontouchstart` or `onmousedown` is triggered. |
| onChange | Function | NOOP | `onChange` will be triggered while the value of Slider changing. |
| onAfterChange | Function | NOOP | `onAfterChange` will be triggered when `ontouchend` or `onmouseup` is triggered. |
| minimumTrackStyle | Object |  | please use  `trackStyle` instead. (`only used for slider, just for compatibility , will be deprecate at rc-slider@9.x `) |
| maximumTrackStyle | Object |  | please use  `railStyle` instead (`only used for slider, just for compatibility , will be deprecate at rc-slider@9.x`) |
| handleStyle | Array[Object] \| Object | `[{}]` | The style used for handle. (`both for slider(`Object`) and range(`Array of Object`), the array will be used for mutli handle follow element order`) |
| trackStyle | Array[Object] \| Object | `[{}]` | The style used for track. (`both for slider(`Object`) and range(`Array of Object`), the array will be used for mutli track follow element order`)|w
| railStyle | Object | `{}` | The style used for the track base color.  |
