1つのペインを別のペインに配線する方法

Question

paneWithListに出力を配線するにはどうすればよいですか？

PaneWithListは、そのJListにリスナーを持ち、選択した行をコンソールに出力します。どのように出力をJTextPaneに送ることができますか？

PaneWithListは、Mainのピックアップイベントを発動できますか？ PropertyChangeSupportで十分でしょうか？

Main.java：

package dur.bounceme.net; 

import javax.swing.JTabbedPane; 

public class Main { 

    private static JTabbedPane tabs; 
    private static PaneWithList paneWithList; 
    private static PaneWithTable paneWithTable; 
    private static Output output; 

    public static void main(String[] args) { 
     tabs = new javax.swing.JTabbedPane(); 
     paneWithList = new PaneWithList(); 
     paneWithTable = new PaneWithTable(); 
     tabs.addTab("list", paneWithList); 
     tabs.addTab("table", paneWithTable); 
     tabs.addTab("output", output); 
    } 
} 

Answer 1

は、ここでまたhere、hereとhere見て、observer patternを使用した例です。コンボのモデルを聞くことも可能であることに注意してください。

import java.awt.GridLayout; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import java.beans.PropertyChangeEvent; 
import java.beans.PropertyChangeListener; 
import javax.swing.*; 

/** 
* @see http://en.wikipedia.org/wiki/Observer_pattern 
* @see https://stackoverflow.com/a/10523401/230513 
*/ 
public class PropertyChangeDemo { 

    public PropertyChangeDemo() { 
     JFrame f = new JFrame(); 
     f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     f.setResizable(false); 
     f.add(new ObserverPanel()); 
     f.pack(); 
     f.setLocationByPlatform(true); 
     f.setVisible(true); 
    } 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 

      @Override 
      public void run() { 
       PropertyChangeDemo example = new PropertyChangeDemo(); 
      } 
     }); 
    } 
} 

class ObserverPanel extends JPanel { 

    private JLabel title = new JLabel("Value received: "); 
    private JLabel label = new JLabel("null", JLabel.CENTER); 

    public ObserverPanel() { 
     this.setBorder(BorderFactory.createTitledBorder("ObserverPanel")); 
     JPanel panel = new JPanel(new GridLayout(0, 1)); 
     panel.add(title); 
     panel.add(label); 
     this.add(panel); 
     ObservedPanel observed = new ObservedPanel(); 
     observed.addPropertyChangeListener(new PropertyChangeListener() { 

      @Override 
      public void propertyChange(PropertyChangeEvent e) { 
       if (e.getPropertyName().equals(ObservedPanel.PHYSICIST)) { 
        String value = e.getNewValue().toString(); 
        label.setText(value); 
       } 
      } 
     }); 
     this.add(observed); 
    } 
} 

class ObservedPanel extends JPanel { 

    public static final String PHYSICIST = "Physicist"; 
    private static final String[] items = new String[]{ 
     "Alpher", "Bethe", "Gamow", "Dirac", "Einstein" 
    }; 
    private JComboBox combo = new JComboBox(items); 
    private String oldValue; 

    public ObservedPanel() { 
     this.setBorder(BorderFactory.createTitledBorder("ObservedPanel")); 
     combo.addActionListener(new ComboBoxListener()); 
     this.add(combo); 
    } 

    private class ComboBoxListener implements ActionListener { 

     @Override 
     public void actionPerformed(ActionEvent ae) { 
      String newValue = (String) combo.getSelectedItem(); 
      firePropertyChange(PHYSICIST, oldValue, newValue); 
      oldValue = newValue; 
     } 
    } 
}

私は自分の参考のためCardLayoutを使用してではなく、JTabbedPane(s)

Answer 3

非常に複雑でレイアウトさ内容で使用JMenu with JMenuItemsだろう、とNetbeansのGUIビルダーを使用して誰のために、これはそう作品それまで通り：

PanelWithListクラス：

package dur.bounceme.net; 

public class PanelWithList extends javax.swing.JPanel { 

    public PanelWithList() { 
     initComponents(); 
    } 

    /**

      public int getSize() { return strings.length; } 
      public Object getElementAt(int i) { return strings[i]; } 
     }); 
     jList1.setSelectionMode(javax.swing.ListSelectionModel.SINGLE_SELECTION); 
     jList1.addMouseListener(new java.awt.event.MouseAdapter() {

     setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); 

     panelWithList1.addPropertyChangeListener(new java.beans.PropertyChangeListener() {

キーがpanelWithList1PropertyChange 'はpanelWithList' 自体にリスナーであることです。

PanelWithList.firePropertyChange("list", -1, 1);は、表示されているオブジェクトも文字列も送信できないため、の値をどのようにJFrameまで選択するのか正確にはわかりません。

ええと、よくAPIには、オブジェクトを送信できると記載されています。それをチェックしてください。

JFrameまでJListが使用しているモデルについての情報を得る必要があると思います。しかし、MVCを破ることはありませんか？あるいは、それは間違ったアプローチです。
