# Modelo Vista Controlador

A idea de esta fase intermedia e engadir un controlador ao noso código anterior, de tal maneira que eliminemos toda a xestión de eventos da parte da vista. Para isto imos a crear un Controlador de Persoas e imos actualizar VentanaPrincipal e instanciar o noso controlador na App

## ControladorPersonas

```java
package Controller;

import modelo.Persona;
import vista.DialogoNuevaPersona;
import vista.DialogoVisualizarPersona;
import vista.VentanaPrincipal;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

public class ControladorPersonas {

    private VentanaPrincipal vista;

    public ControladorPersonas(VentanaPrincipal vista){
        this.vista=vista;
        this.inicializar();
    }

    private void inicializar(){
        cargarTabla();

        //Gestionamos los eventos asociados al boton de crear personas
        vista.getPanelInferior().getBtnNuevaPersona().addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // Abrimos el diálogo pasando la ventana y el panel central
                DialogoNuevaPersona dialogo = new DialogoNuevaPersona(vista, vista.getPanelCentro());
                dialogo.setVisible(true);
                cargarTabla();
            }
        });

        vista.getPanelCentro().getTabla().addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                int fila = vista.getPanelCentro().getTabla().getSelectedRow();
                Persona persona = vista.getPanelCentro().getPersona(fila);
                DialogoVisualizarPersona dialogo = new DialogoVisualizarPersona(vista, persona);
                dialogo.setVisible(true);
            }
        });
    }

    private void cargarTabla(){

    }

}

```

## VentanaPrincipal

A idea principal neste punto é que **a vista NON xestiona os eventos, é unha responsabilidade do controlador.**

```java
package vista;

import modelo.Persona;

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;


public class VentanaPrincipal extends JFrame {

    private PanelSuperior panelSuperior;
    private PanelCentral panelCentro;
    private PanelInferior panelInferior;

    public VentanaPrincipal(){
        setTitle("Gestión de Personas");
        setSize(600,400);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setLayout(new BorderLayout());

        this.panelSuperior = new PanelSuperior();
        this.panelCentro = new PanelCentral();
        this.panelInferior = new PanelInferior();

        panelSuperior.setBackground(Color.GREEN);
        panelCentro.setBackground(Color.YELLOW);
        panelInferior.setBackground(Color.CYAN);
        //Dimensiones
        panelSuperior.setPreferredSize(new Dimension(600, 80));
        panelInferior.setPreferredSize(new Dimension(600, 60));
        //Añadimos los paneles al frame
        this.add(panelSuperior, BorderLayout.NORTH);
        this.add(panelCentro, BorderLayout.CENTER);
        this.add(panelInferior, BorderLayout.SOUTH);
        
        setVisible(true);
    }

    public PanelSuperior getPanelSuperior() {
        return panelSuperior;
    }

    public PanelCentral getPanelCentro() {
        return panelCentro;
    }

    public PanelInferior getPanelInferior() {
        return panelInferior;
    }
}

```

## App

Na clase principal imos ter que inicializar a nosa vista e o noso controlador.

```java
public class App {

    public static void main(String[] args) {
        VentanaPrincipal ventana = new VentanaPrincipal();
        ControladorPersonas controladorPersonas = new ControladorPersonas(ventana);
    }
}
```
