jTree 修改节点值

思路如下：

1.取得当前的节点

2.获取节点的userobject

3.设置新的节点值object

 

//1.取得当前所在的节点 DefaultMutableTreeNode selectedTreeNode = null; selectedTreeNode = (DefaultMutableTreeNode) leftScrollPanel.getJTree().getLastSelectedPathComponent(); if(selectedTreeNode!=null) { Object userObject = new JTreeData((int) opInfo.getOperatorId(), opInfo.getName(), StatPic.MANAGER_USER); //2.设置userobject的值 selectedTreeNode.setUserObject(userObject); leftScrollPanel.getJTree().updateUI(); }
