## 使用

### 使用单独的Tree包
#### 组件引入
先进行下载Tree包
```
npm install --save bee-tree
```
组件调用
```js
import Tree from 'bee-tree';

const TreeNode = Tree.TreeNode;

const defaultProps = {
	keys: ['0-0-0', '0-0-1']
}
class Demo1 extends Component {
	constructor(props) {
		super(props);
	    const keys = this.props.keys;
	    this.state = {
	      defaultExpandedKeys: keys,
	      defaultSelectedKeys: keys,
	      defaultCheckedKeys: keys,
	    };
	}
	onSelect(info) {
	    console.log('selected', info);
	}
	onCheck(info) {
	    console.log('onCheck', info);
	}
	render() {
	    return (
	      <Tree className="myCls" showLine checkable
	        defaultExpandedKeys={this.state.defaultExpandedKeys}
	        defaultSelectedKeys={this.state.defaultSelectedKeys}
	        defaultCheckedKeys={this.state.defaultCheckedKeys}
	        onSelect={this.onSelect} onCheck={this.onCheck}
	      >
	        <TreeNode title="parent 1" key="0-0">
	          <TreeNode title="parent 1-0" key="0-0-0" disabled>
	            <TreeNode title="leaf" key="0-0-0-0" disableCheckbox />
	            <TreeNode title="leaf" key="0-0-0-1" />
	          </TreeNode>
	          <TreeNode title="parent 1-1" key="0-0-1">
	            <TreeNode title={<span style={{ color: '#08c' }}>sss</span>} key="0-0-1-0" />
	          </TreeNode>
	        </TreeNode>
	      </Tree>
	    );
	}
}

React.render(<Demo1 />, document.getElementById('target'));
```
#### 样式引入
- 可以使用link引入dist目录下tree.css
```
<link rel="stylesheet" href="./node_modules/build/bee-tree.css">
```
- 可以在js中import样式
```js
import "./node_modules/src/Tree.scss"
//或是
import "./node_modules/build/bee-tree.css"
```




## API

onCheck|当选择事件发生触发的方法|function(checkedKeys, e:{checked: bool, checkedNodes, node, event})|-
onSelect|当用户选择树节点触发的回调函数|function(selectedKeys, e:{selected: bool, selectedNodes, node, event})|-
filterTreeNode|过滤树节点的方法（highlight）,当返回true,相关联的节点会高亮|function(node)|-

draggable|树是否可拖拽（IE>8|	bool|false
onDragStart|当树节点刚开始拖拽所触发的放方法|function({event,node})|-
onDragEnter|当拖拽进入触发的方法|function({event,node,expandedKeys})|-
onDragOver|当拖拽经过触发的方法|function({event,node})|-
onDragLeave|当拖拽离开触发的方法|function({event,node})|-
onDragEnd当拖拽结束触发的方法|function({event,node})|-
onDrop|当节点放下触发方法function({event, node, dragNode, dragNodesKeys})|-
onDoubleClick|当双击发生触发的方法|function(checkedKeys, e:{node, event})|-
Children|必填，TreeNode组件|node|-
|mustExpandable|支持disabled的节点可以自定义展开收起，默认disabled的节点不可以展开收起|bool|false
