drawString() won't draw

Question

As it stands I'm trying to draw a string off a component into a frame, the SSCCE would be something like this:

// The component class through which I draw the string!
package gui;

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JPanel;
import javax.swing.border.LineBorder;

public class PanelEstado extends JPanel{

    private String valores = "";

    protected void paintComponent(Graphics g){

        super.paintComponent(g);
        g.setColor(Color.BLACK);

        g.drawString(valores, 400, 45);

    }

    public void setValores(int arca, int puntosBelleza, int cantidadHabitantes, int cantidadHabitantesDisponibles){

        String valores = "Arca: " + arca 
                + "                                    " 
                + " Puntos de Belleza: " + puntosBelleza + 
                "                                    " + 
                " Habitantes: " + 
                cantidadHabitantes + " / " 
                + cantidadHabitantesDisponibles;
    }

    public PanelEstado(){
        setBorder(new LineBorder(Color.RED));
    }


}

// The Main GUI Class!

public GUIJuego(){

    JPanel panelConstruccion = new JPanel(new GridLayout(9,1));
    JPanel panelDatosCiudad = new JPanel(new GridLayout(1,2));
    JPanel panelMapa = new JPanel(new GridLayout(25,25));
    PanelEstado panEst = new PanelEstado();
        add(panelConstruccion, BorderLayout.WEST);

    add(panelDatosCiudad, BorderLayout.NORTH);
    panelDatosCiudad.add(labelConstrucciones);
    panEst.setValores(administrador.getCiudad().getArca(), administrador.getCiudad().getPuntosBelleza(), administrador.getCiudad().getCantidadHabitantes(), administrador.getCiudad().getCantidadHabitantesDisponibles());
    panelDatosCiudad.add(panEst);
    add(panelMapa, BorderLayout.CENTER);
}

Let me narrow your search down a bit. The most important part of this would be the first class in the SSCCE and this:

    panEst.setValores(administrador.getCiudad().getArca(), administrador.getCiudad().getPuntosBelleza(), administrador.getCiudad().getCantidadHabitantes(), administrador.getCiudad().getCantidadHabitantesDisponibles());
    panelDatosCiudad.add(panEst);

Now, as it stands, the border within the constructor of my Component does show up and is right where I want it to be, but the String that I want to draw is nowhere to be seen. Am I missing something, or doing something wrong?

Thanks,

You didn't override the getPreferredSize() method of the PanelEstado class, so the size is zero so the component is never painted.

Why are you even using a panel for this. What is wrong with a JLabel and the using the setText(...) method. Then you don't need to worry about setting the preferred size.
