Drgging a node and move it to another one will merge those two nodes.


Right click on blank canvas will generate a new node.


Right click on a node will remove this node and it's descendents nodes if it contains children.


rData is hierarchy tree object and it will changed accrodingly with this pack tree.


拖拽一个节点并靠近另一个将会使得这两个节点融合；


右键单击空白区域产生新的节点；


右键单击节点将删除该节点及其包含的子节点；


rData 是一个树对象，其会随着节点的增加和减少而变化。
