JXTreeTable Exemple modifiable?

Question

Y at-il un exemple de travail pour Editable JxTreeTable .. J'ai essayé quelques méthodes. Mais pas de chance ... Seule la première colonne est modifiable.

Comment rendre toutes les colonnes modifiables?

Désolé les gars,

Voici mon code src:

@Override 
public Object getValueAt(Object arg0, int arg1) { 
    if (arg1 == 1) { 
     return new String("hi " + arg0.toString()); 
    } 
    return arg0; 
} 
} 

Merci .... Je veux modifier toutes les colonnes. Mais ce code ne fonctionne qu'avec la première colonne.

Voici un exemple rapide, étapes simples

• implémentent une TreeTableNode coutume editiable, l'extension AbstractMutableTreeTableNode
• utilisation que dans un DefaultTreeTableModel
• instancier un JXTreeTable avec le modèle

Dans le code :

/** 
* A custom node implementation. 
*/ 
public static class ArrayNode extends AbstractMutableTreeTableNode { 

    public ArrayNode(Object[] data) { 
     super(data); 
    } 

    @Override 
    public Object getValueAt(int column) { 
     return getUserObject()[column]; 
    } 

    @Override 
    public void setValueAt(Object aValue, int column) { 
     getUserObject()[column] = aValue; 
    } 

    @Override 
    public int getColumnCount() { 
     return 2; 
    } 

    @Override 
    public Object[] getUserObject() { 
     return (Object[]) super.getUserObject(); 
    } 

    @Override 
    public boolean isEditable(int column) { 
     return true; 
    } 

} 

// usage 
ArrayNode root = new ArrayNode(new Object[] {"root", ""}); 
for (int i = 0; i < 5; i++) { 
    root.add(new ArrayNode(new Object[]{"child", "" + i})); 
} 
JXTreeTable table = new JXTreeTable(new DefaultTreeTableModel(root));
