在JBable中使JButton可单击 [英] Making a JButton clickable inside a JTable

问题描述

以下是我想要做的截图：

Here is the screenshot of what I want to do :

正在发生的事情是JButton正确显示但是当我点击它时没有任何反应。
经过一些搜索，我发现 table.getValueAt（）返回的 Object 是一个字符串而不是JButton ...

What's happening there is the JButton shows correctly but nothing happens when I click on it. After some search, I've found that the Object returned by table.getValueAt() is a String instead of a JButton...

以下是代码：

tblResult = new JTable(data,cols) {
    public TableCellRenderer getCellRenderer( int row, int column ) {
        return new ClientsTableRenderer();
    }
};

我用它在运行时填充JTable：
（ tblResult 现在 Clients.rblResult ）

I use this for populating at run-time the JTable : (tblResult is now Clients.rblResult)

SwingUtilities.invokeLater( new Runnable() {
    public void run() { 

        DefaultTableModel aModel = new DefaultTableModel() {
            //setting the jtable read only
            @Override
            public boolean isCellEditable(int row, int column) {
                return false;
            }               
        };


    String[] cols = {"N°","Société", "TVA", "CP", "Ville", ""};
    aModel.setColumnIdentifiers(cols);

    Object[] temp = new Object[6];
    for(int i=0;i<result.length;i++) {

        temp[0] = result[i].custNumber;
        temp[1] = result[i].name;
        temp[2] = result[i].tva;
        temp[3] = result[i].cp;
        temp[4] = result[i].city;
        temp[5] = "Consulter";

        aModel.addRow(temp);

    }

    Clients.tblResult.setModel(aModel);

    Clients.tblResult.addMouseListener(new JTableButtonMouseListener(Clients.tblResult));
    }}  
); 

此处 ClientsTableRenderer class

public class ClientsTableRenderer extends JPanel implements TableCellRenderer {
    @Override
    public Component getTableCellRendererComponent( final JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        setBackground(Color.WHITE);
        if(column < 5) {
            JLabel label =  new JLabel(value.toString());
            JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER,0,9));
            panel.setBackground(Color.WHITE);
            panel.add(label);
            this.add( panel);
        } else {

            JButton button = new JButton(value.toString());
            button.addActionListener(new ActionListener() {
                @Override
                public void actionPerformed(ActionEvent arg0) {
                    System.out.println("Clicked !");
                }
            });
            JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER,0,3));
            panel.setBackground(Color.WHITE);
            panel.add(button);
            this.add(panel);
        }


        return this;
    }


}

最后， JTableButtonMouseListener（）：

And finaly, the JTableButtonMouseListener() :

public class JTableButtonMouseListener extends MouseAdapter {
      private final JTable table;

      public JTableButtonMouseListener(JTable table) {
        this.table = table;
      }

      @Override public void mouseClicked(MouseEvent e) {
        int column = table.getColumnModel().getColumnIndexAtX(e.getX());
        int row    = e.getY()/table.getRowHeight(); 
        System.out.println("Col :"+column + "row:"+row);

        if (row < table.getRowCount() && row >= 0 && column < table.getColumnCount() && column >= 0) {
          Object value = table.getValueAt(row, column);
          System.out.println("Value :"+value.getClass().getName());
          if (value instanceof JButton) {
            ((JButton)value).doClick();
          }

        }
      }
    }
