Note: parent and children nodes are associated, if the parent node's key exists, it all children node will be checked, and vice versa. When set checkable and checkStrictly, it should be an object, which contains checked array and halfChecked array. | String[]/{checked:Array<String>,halfChecked:Array<String>} | [] |

+| onCheck | click the treeNode/checkbox to fire | function(checkedKeys, e:{checked: bool, checkedNodes, node, event, nativeEvent}) | - |
+| onExpand | fire on treeNode expand or not | function(expandedKeys, {expanded: bool, node, nativeEvent}) | - |
+| onDragEnd | it execs when fire the tree's dragend event | function({event,node}) | - |
+| onDragEnter | it execs when fire the tree's dragenter event | function({event,node,expandedKeys}) | - |

+| onDrop | it execs when fire the tree's drop event | function({event, node, dragNode, dragNodesKeys}) | - |
+| onLoad | Trigger when a node is loaded. If you set the `loadedKeys`, you must handle `onLoad` to avoid infinity loop | function(loadedKeys, {event, node}) | - |
+| onMouseEnter | call when mouse enter a treeNode | function({event,node}) | - |
+| onMouseLeave | call when mouse leave a treeNode | function({event,node}) | - |
+| onRightClick | select current treeNode and show customized contextmenu | function({event,node}) | - |
+| onSelect | click the treeNode to fire | function(selectedKeys, e:{selected: bool, selectedNodes, node, event, nativeEvent}) | - |
+| switcherIcon | specific the switcher icon. | ReactNode / (props: TreeNodeAttribute) => ReactNode | - |

+| expandAction | Tree open logic, optional: false \| `click` \| `doubleClick` | string \| boolean | `click` |
+
+### TreeNode props
+
+> note: if you have a lot of TreeNode, like more than 1000,  
+> make the parent node is collapsed by default, will obvious effect, very fast.  
+> Because the children hide TreeNode will not insert into dom.
+
+| name | description | type | default |
+| --- | --- | --- | --- |
+| className | additional class to treeNode | String | '' |
+| checkable | control node checkable if Tree is checkable | bool | false |

+| disabled | whether disabled the treeNode | bool | false |
+| disableCheckbox | whether disable the treeNode' checkbox | bool | false |
+| title | tree/subTree's title | String/element/((data: DataNode) => React.ReactNode) | '---' |
+| key | it's used with tree props's (default)ExpandedKeys / (default)CheckedKeys / (default)SelectedKeys. you'd better to set it, and it must be unique in the tree's all treeNodes | String | treeNode's position |
+| isLeaf | whether it's leaf node | bool | false |
+| icon | customize icon. When you pass component, whose render will receive full TreeNode props as component props | element/Function(props) | - |
+| switcherIcon | specific the switcher icon. | ReactNode / (props: TreeNodeAttribute) => ReactNode | - |
+
+## Note
+
+The number of treeNodes can be very large, but when enable `checkable`, it will spend more computing time, so we cached some calculations(e.g. `this.treeNodesStates`), to avoid double computing. But, this bring some restrictions, **when you async load treeNodes, you should render tree like this** `{this.state.treeData.length ? <Tree ...>{this.state.treeData.map(t => <TreeNode ... />)}</Tree> : 'loading tree'}`
