Da erro nesta linha:

[code] public Component PopupMenu(){
popupmenu = new JPopupMenu(“Monitor da Rede”);
jpopMI = new JMenuItem(“Atualizar”);
jpopMI.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent evt){
top.removeAllChildren();
criaNodes(top);
tree.updateUI();
}
});

    popupmenu.add(jpopMI);
    
    add(popupmenu); <------------AQUI
    enableEvents(AWTEvent.MOUSE_EVENT_MASK);
    return popupmenu;
}[/code]

Já tentei usar o contentor.add(); ou MonitorDaRede.contentor.add();

Mas não consigo descobrir onde.
