Bom galera, estou desenvolvendo uma aplicação aqui em que coloco em um JTree o historico dos usuários do sistema.
Crio e faço a inserção dos nodos na arvore, mas quando mostra na tela, soh aparece o JTree, definido por default no NetBeans.
Gostaria de saber como atualizar os nodos da arvore, considerando os valores que construo
Abaixo segue o codigo:
package GUI;
import DAO.DAOBase;
import Util.Par;
import java.awt.Dimension;
import java.awt.Toolkit;
import java.util.Vector;
import javax.swing.JPanel;
import javax.swing.JTree;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;

public class Historico extends javax.swing.JDialog {
private Vector hist;
private JTree Arvore;
/** Creates new form Historico */
public Historico(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
// centraliza aplicacao
Toolkit tk = Toolkit.getDefaultToolkit();
Dimension screenSize = tk.getScreenSize();
this.setLocation((screenSize.width - this.getSize().width) / 2,
(screenSize.height - this.getSize().height) / 2);
System.gc();
jLblUsuario.setText(Principal.getUsuario().getNome());
// recupera o historico para montar a arvore
hist = DAOBase.recupera_historico(Principal.getUsuario().getId());
preencheArvore(hist);
}
public void preencheArvore(Vector hist){
DefaultMutableTreeNode raiz = montarArvore(hist);
jTree1 = new JTree(raiz);
}
private DefaultMutableTreeNode montarArvore(Vector hist){
Par p;
String[] invs;
DefaultMutableTreeNode raiz = new DefaultMutableTreeNode("Histórico");
DefaultMutableTreeNode subno;
for(int i = 0; i < hist.size(); i ++){
p = (Par)hist.get(i);
subno = new DefaultMutableTreeNode(formataData(p.getDate().toString()));
System.out.println(formataData(p.getDate().toString()));
invs = p.getInvs().split(",");
for( int j = 0; j < invs.length; j ++ ){
System.out.println(" >> " + invs[j]);
subno.add(new DefaultMutableTreeNode(invs[j]));
}
raiz.add(subno);
}
return raiz;
}
