Swing propojení s greenfoot – Java – Fórum – Programujte.com

 Zdravím,

potřeboval bych poradit, co dělám blbě při propojení greenfootu se swingem. 

 Problém je v tom, že jak kliknu na actora, tak se mi pouze zastaví greenfoot, ale neobjeví se okno swingu.

class ZooActor extends Actor {

    private Zoo zoo;
    private ZooPanel zooPanel;

    public ZooActor(Zoo zoo) {
        this.zooPanel = new ZooPanel();
        this.zoo = zoo;
        this.zooPanel.setZoo(zoo);
        setImage("images/zoo.png");
    }

    @Override
    public void act() {
        if (Greenfoot.mouseClicked(this)) {
            Greenfoot.stop();
            zooPanel.setZoo(zoo);
            SwingUtilities.invokeLater(() -> zooPanel.setVisible(true));

        }
    }

}

public class ZooPanel extends javax.swing.JPanel {
 private static final String MONEY_FORMAT = "%.2f";
   
    public ZooPanel() {
        initComponents();
    }

    Zoo zoo;

    public void setZoo(Zoo zoo) {
        this.zoo = zoo;      
        this.updateMoney();
        this.zoo.getMoney().addPropertyChangeListener(evt -> updateMoney());
    }
    
      
    
     private void updateMoney() {
        jTextField2.setText(String.format(MONEY_FORMAT, zoo.getMoney().getMoney())
        );
    }
     

    
    
    /**

        jLabel1 = new javax.swing.JLabel();

        addComponentListener(new java.awt.event.ComponentAdapter() {
            public void componentHidden(java.awt.event.ComponentEvent evt) {
                formComponentHidden(evt);
            }
        });

        jTextField2.setEditable(false);

        jLabel1.setText("Money");

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(this);
        this.setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)

        );
    }// </editor-fold>                        

    private void formComponentHidden(java.awt.event.ComponentEvent evt) {                                     
                                          
      Greenfoot.start();
     
    }                                    
 

    // Variables declaration - do not modify

Děkuji.

Co je greenfood nevím ale abys zobrazil ve swingu okno tak ho musíš dát do Jframe. Pak dát tomu framu setVisible. Samotný JPanel je pouze obsah okna ne okno... Tj vytvoř si JFrame a přidej do něj ten panel.
