JPanels JFrame'de nasıl gösterilir/gizlenir?

Question

Geliştirdiğim uygulama bir oyundur. Yapmak istediğim, JFrame'de görünen bir metin veya mesaj penceresi gibi görünen ve artık kullanılmadığı zaman yok olan JPanels'tir. Bu JPanel'leri Netbeans'te harici sınıflar olarak tasarladım ve bunları bir actionPerformed() yönteminde çağırmak istiyorum. JOptionPanes veya diğer açılan diyaloglar bir seçenek değildir çünkü odaklanmayı oyundan uzaklaştırırlar. Ayrıca birisinin benzer bir soruda CardLayout önerdiğini gördüm. İstediğim şey bu değil çünkü sadece bölmeleri değiştirmeye çalışmıyorum. Program onlara söylediğinde gitmeliler. Bunu, JButton Eylemine bağlayarak nasıl söylerim?

Answer 1

setVisible(false) numaralı telefonu arayarak JPanel'i gizleyebilirsiniz. parent içeri karesinin ve panel Eklemek istediğiniz paneli kapsayıcıdır

public static void main(String args[]){ 
    JFrame f = new JFrame(); 
    f.setLayout(new BorderLayout()); 
    final JPanel p = new JPanel(); 
    p.add(new JLabel("A Panel")); 
    f.add(p, BorderLayout.CENTER); 

    //create a button which will hide the panel when clicked. 
    JButton b = new JButton("HIDE"); 
    b.addActionListener(new ActionListener(){ 
     public void actionPerformed(ActionEvent e){ 
       p.setVisible(false); 
     } 
    }); 

    f.add(b,BorderLayout.SOUTH); 
    f.pack(); 
    f.setVisible(true); 
}
