Question

我有一个7列的JTable。我想在七一列添加带有Icon的JButton。

所以我有这个：

mappa= modelManager.getContoBancarioManager().getContiBancari(null,WFConst.CONTO_BANCARIO_PUBBLICO);
//fontTable = new Font("Century Gothic", Font.PLAIN, 15);
tableModelContiBancari = new MyTableModelContiBancari();
tableContiBancari= new JTable(tableModelContiBancari);

tableModelContiBancari.stampaTabella(mappa);
tableContiBancari.addMouseListener(new MyMouseAdapterTableConti());
jScrollPane = new JScrollPane();
jScrollPane.setViewportView(tableContiBancari);
jScrollPane.setPreferredSize(dTabella);


Toolkit t = Toolkit.getDefaultToolkit();
Dimension screenSize = t.getScreenSize();
Double larghezza =screenSize.getWidth()*0.95;
//    System.out.println(larghezza);
int lar = (int) (larghezza /90);
int lar2 = (int)(larghezza /5);
tableContiBancari.getColumnModel().getColumn(0).setPreferredWidth(10);
tableContiBancari.getColumnModel().getColumn(1).setPreferredWidth(lar2);
tableContiBancari.getColumnModel().getColumn(2).setPreferredWidth(lar);
tableContiBancari.getColumnModel().getColumn(3).setPreferredWidth(lar);
tableContiBancari.getColumnModel().getColumn(4).setPreferredWidth(lar);
tableContiBancari.getColumnModel().getColumn(5).setPreferredWidth(lar);
tableContiBancari.getColumnModel().getColumn(6).setPreferredWidth(lar);

Action delete = new AbstractAction()
{
    public void actionPerformed(ActionEvent e)
    {
    //to do
    System.out.println("pp");
    }
};

ButtonColumn buttonColumn = new ButtonColumn(tableContiBancari, delete, 7);
buttonColumn.setMnemonic(KeyEvent.VK_D);

这是ButtonColumn类：

public void daiProprietaJTableContiBancari(){
    mappa= modelManager.getContoBancarioManager().getContiBancari(null,WFConst.CONTO_BANCARIO_PUBBLICO);
    //fontTable = new Font("Century Gothic", Font.PLAIN, 15);
    tableModelContiBancari = new MyTableModelContiBancari();
    tableContiBancari= new JTable(tableModelContiBancari);
    tableContiBancari.addKeyListener(new KeyAdapter() {
        @Override
        public void keyReleased(KeyEvent e) {
            if(e.getKeyCode() == KeyEvent.VK_F5)
                cambiaTipologiaConti();
        }
    });
    tableModelContiBancari.stampaTabella(mappa);
    //tableContiBancari.setFont(fontTable);
    tableContiBancari.addMouseListener(new MyMouseAdapterTableConti());
    jScrollPane = new JScrollPane();
    jScrollPane.setViewportView(tableContiBancari);
    jScrollPane.setPreferredSize(dTabella);

    tableContiBancari.setRowHeight(25);

    Toolkit t = Toolkit.getDefaultToolkit();
    Dimension screenSize = t.getScreenSize();
    Double larghezza =screenSize.getWidth()*0.95;
    //    System.out.println(larghezza);
    int lar = (int) (larghezza /90);
    int lar2 = (int)(larghezza /5);
    tableContiBancari.getColumnModel().getColumn(0).setPreferredWidth(10);
    tableContiBancari.getColumnModel().getColumn(1).setPreferredWidth(lar2);
    tableContiBancari.getColumnModel().getColumn(2).setPreferredWidth(lar);
    tableContiBancari.getColumnModel().getColumn(3).setPreferredWidth(lar);
    tableContiBancari.getColumnModel().getColumn(4).setPreferredWidth(lar);
    tableContiBancari.getColumnModel().getColumn(5).setPreferredWidth(lar);
    tableContiBancari.getColumnModel().getColumn(6).setPreferredWidth(lar);

    DefaultTableCellRenderer renderer_archivi = new DefaultTableCellRenderer();
    renderer_archivi.setHorizontalAlignment(SwingConstants.RIGHT);
    tableContiBancari.getColumnModel().getColumn(4).setCellRenderer(renderer_archivi);
    tableContiBancari.getColumnModel().getColumn(5).setCellRenderer(renderer_archivi);
    tableContiBancari.getColumnModel().getColumn(6).setCellRenderer(renderer_archivi);

    Action delete = new AbstractAction()
    {
        public void actionPerformed(ActionEvent e)
        {
        //to do
        System.out.println("pp");
        }
    };

    ButtonColumn buttonColumn = new ButtonColumn(tableContiBancari, delete, 7);
    buttonColumn.setMnemonic(KeyEvent.VK_D);
    //tableContiBancari.getColumnModel().getColumn(7).setCellRenderer(new ButtonRenderer());
    //tableContiBancari.getColumnModel().getColumn(7).setCellEditor(new ButtonEditor(new JCheckBox()));
    //setUpColumnButton(tableContiBancari, tableContiBancari.getColumnModel().getColumn(7));
}

如果我尝试运行代码，我在最后一列有一个带JButton的JTable，但是如果我尝试点击一个JButton，那么该动作就不会执行。

Answer 1

您需要实现自己的TableCellRenderer并使其方法getTableCellRendererComponent为您的列返回JButton。请参阅Tutorial。

Answer 2

查看http://jsfiddle.net/zs860fLx/2/一种方法。

您可以像对任何其他列一样向列中添加文本，然后将ButtonColumn类用作：

renderer - 以便文本显示在按钮上
editor - 所以你可以点击按钮来调用一个动作。

您还必须向Action课程提供ButtonColumn。 Action可以访问所点击按钮的行。例如，您可以轻松使用行号删除行，或使用该行从表中获取数据并执行其他处理。
