Jtree-对后台传来的数据报文动态创建树节点

摘要: 对后台传来的数据报文[[态名，应用名，节点名],[态名，应用名，节点名],。。。]需要动态的进行创建树节点。



//左侧树创建

public JTree refreshTreeTable(){

//eventOneInfo为传来的数据报文Vector<Vector<String>> eventOneInfo ;

//[[4,realtime,public,scd1],[4,realtime,public,scd2],[4,realtime,public_2,scd2], [4,realtime,public_3,scd2]]
if (eventOneInfo.isEmpty()) {
// 树的数据模型
treemodel = new DefaultTreeModel(root);
// 设置数据模型
jTree = new JTree();
jTree.setModel(treemodel);
jTree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
jTree.setRootVisible(false);
jTree.updateUI();

}
SwingUtilities.invokeLater(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub

for (int i = 0; i < eventOneInfo.size(); i++) {
Vector<String> element_one=eventOneInfo.elementAt(i);
DefaultMutableTreeNode node1_one = new DefaultMutableTreeNode(element_one.get(1).trim());
DefaultMutableTreeNode node1_two = new DefaultMutableTreeNode(element_one.get(2).trim());
DefaultMutableTreeNode node1_three = new DefaultMutableTreeNode(element_one.get(3).trim());

node1_one =searchNode(element_one.elementAt(1).trim(), root);
if (node1_one != null) {
node1_two =searchNode(element_one.elementAt(2).trim(), node1_one);
if (node1_two != null) {

sp; node1_three =searchNode(element_one.elementAt(3).trim(), node1_two);
if (node1_three != null) {

}else {
node1_three = new DefaultMutableTreeNode(element_one.elementAt(3).trim());
treemodel.insertNodeInto(node1_three, node1_two, node1_two.getChildCount());
// ((DefaultTreeModel)jTree.getModel()).insertNodeInto(node1_three, node1_two, node1_two.getChildCount());
}

}else {
node1_two = new DefaultMutableTreeNode(element_one.elementAt(2).trim());
node1_two.add(node1_three);
treemodel.insertNodeInto(node1_two, node1_one, node1_one.getChildCount());
// ((DefaultTreeModel)jTree.getModel()).insertNodeInto(node1_two, node1_one, node1_one.getChildCount());

}else {
node1_one = new DefaultMutableTreeNode(element_one.elementAt(1).trim());
node1_two.add(node1_three);
node1_one.add(node1_two);

}

}

// 设置数据模型
jTree = new JTree();
jTree.setModel(treemodel);
jTree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
jTree.setRootVisible(false);
jTree.updateUI();

return jTree;
