private void Mon_arbreTreeCollapsed(javax.swing.event.TreeExpansionEvent evt) {                                        
// TODO add your handling code here:
 
        ArrayList list = new ArrayList();
        RuleTree t= new RuleTree(T.rootNode);
        list =  t.getState();
        try{
            for(int i=0;i<list.size();i++){
 
                objet_rac_fils ob =(objet_rac_fils)list.get(i);
                JCheckBox rac = (JCheckBox) ob.noeud;
                JCheckBox fil = (JCheckBox) ob.fils;
                if (fil.isSelected() && rac.isSelected()==false && rac.getText().equals("text de checkBox de racine")==false)
                    rac.setForeground(new Color(255,0,0));
                fil.setForeground(new Color(0,0,0));
            }
        }catch(Exception r){r.printStackTrace();}

Avec : la classe Rule est comme suit:

        }
 
 
        list = new ArrayList(list);
        return list;
    }
}

et voici la classe "objet_rac_fils"
