| onExpand | fire on treeNode expand or not | function(expandedKeys, {expanded: bool, node}) | - |
| onCheck | click the treeNode/checkbox to fire | function(checkedKeys, e:{checked: bool, checkedNodes, node, event}) | - |
| onSelect | click the treeNode to fire | function(selectedKeys, e:{selected: bool, selectedNodes, node, event}) | - |
| filterTreeNode | filter some treeNodes as you need. it should return true | function(node) | - |
| loadData | load data asynchronously and the return value should be a promise | function(node) | - |
| onRightClick | select current treeNode and show customized contextmenu | function({event,node}) | - |

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.

| title | tree/subTree's title | String/element | '---' |
| 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 |
