TableCellEditor類不工作

Question

我想在每一行的末尾添加按鈕，到目前爲止我已經使用cellRenderer來做這件事。而且我已經成功地在快照中的每一行中顯示按鈕。 但是，當我點擊按鈕沒有行動發生。 我想點擊按鈕時調用一個新框架。 下面是我的源代碼：

1.對於填充的JTable

try 
{ 
    String url="jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=c:\\ninedots.accdb"; 
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); 
    Connection con=DriverManager.getConnection(url); 
    String sql1="SELECT RMA_No,CallDate,Source,Item,BookingDesc,Customer,Contact,CallType,CallMode,MaterialRequired,TotalMaterialRequiredCost,AssignedTo,CallStatus FROM RMA_Master WHERE (((CallDate) Between #"+fromdate1+"# And #"+todate1+"#)) AND CallStatus='"+Status+"'"; 
    PreparedStatement pst=con.prepareStatement(sql1); 
    ResultSet rs=pst.executeQuery(); 
    dtm=(DefaultTableModel) DbUtils.resultSetToTableModel(rs); 
    dtm.addColumn("Action");     
    table.setModel(dtm); 
    table.getColumn("Action").setCellRenderer(new ButtonCellRenderer()); 
    table.getColumn("Action").setCellEditor(new ButtonCellEditor()); 
    rs.close(); 
    pst.close(); 
    con.close(); 
} 
catch(Exception ex) 
{ 
    System.err.print("Exception: "); 
    System.err.println(ex.getMessage()); 
} 

2.ButtonCellRenderer類

public class ButtonCellRenderer extends JButton implements TableCellRenderer { 

    @Override 
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { 
     if (value != null) { 
      setText("Edit" + value.toString()); 
     } else { 
      setText("Edit");    
     } 
     if (isSelected) { 
      setForeground(table.getSelectionForeground()); 
      setBackground(table.getSelectionBackground()); 
     } else { 
      setForeground(table.getForeground()); 
      setBackground(UIManager.getColor("Button.background")); 
     } 
     return this; 
    } 
} 

3.ButtonCellEditor類

public class ButtonCellEditor extends AbstractCellEditor implements TableCellEditor { 

    /** 
* 
*/ 
private static final long serialVersionUID = 1L; 
    private JButton editor; 
    private Object value; 
    private int row; 
    private JTable table; 

    public ButtonCellEditor() { 
     editor = new JButton(); 
     editor.addActionListener(new ActionListener() { 
      @Override 
      public void actionPerformed(ActionEvent e) { 
       // TODO Auto-generated method stub 
        if (table != null) { 
         fireEditingStopped(); 
         TableModel model = table.getModel(); 
         if (model instanceof DefaultTableModel) { 
          ((DefaultTableModel) model).removeRow(row); 
         } 
        } 
      } 
     }); 
    } 

    @Override 
    public boolean isCellEditable(EventObject e) { 
     return true; 
    } 

    @Override 
    public Object getCellEditorValue() { 
     return value; 
    } 

    @Override 
    public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) { 
     this.table = table; 
     this.row = row; 
     this.value = value; 
     if (value != null) { 
      editor.setText("Delete row " + value.toString()); 
     } else { 
      editor.setText("Delete Me"); 
     } 
     if (isSelected) { 
      editor.setForeground(table.getSelectionForeground()); 
      editor.setBackground(table.getSelectionBackground()); 
     } else { 
      editor.setForeground(table.getForeground()); 
      editor.setBackground(UIManager.getColor("Button.background")); 
     } 
     return editor; 
    } 


} 

請推薦的解決方案對於繼Problem.or我在哪裏做錯了？

Answer 1

檢出Table Button Column爲自定義渲染器/編輯器，允許您將自定義Action按鈕添加到任何列。

你寫的唯一的代碼是Action所以很容易實現：

Action delete = new AbstractAction() 
{ 
    public void actionPerformed(ActionEvent e) 
    { 
     JTable table = (JTable)e.getSource(); 
     int modelRow = Integer.valueOf(e.getActionCommand()); 
     ((DefaultTableModel)table.getModel()).removeRow(modelRow); 
    } 
};
