如何在与带有按钮渲染器和单元格渲染器的表格行同一行的单击按钮上获取表格行的数据？

Question

我已经实现了带有单元格渲染器的自定义表格，以便我可以在表格中的每一行添加删除按钮

按钮编辑器.java

public class ButtonEditor extends DefaultCellEditor{
    protected TableButton btn;
    private String lbl;
    private Boolean clicked;

    public ButtonEditor(JTextField txt) {
        super(txt);

        btn= new TableButton();
        btn.setOpaque(true);

        //WHEN BUTTON IS CLICKED
        btn.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
//                fireEditingStopped();
                JOptionPane.showMessageDialog(btn, lbl+" Clicked");
            }
        });
    }

   //OVERRIDE A COUPLE OF METHODS
    @Override
    public Component getTableCellEditorComponent(JTable table, Object obj,
        boolean selected, int row, int col) {

        //SET TEXT TO BUTTON,SET CLICKED TO TRUE,THEN RETURN THE BTN OBJECT
        lbl=(obj==null) ? "":obj.toString();
        btn.setText(lbl);
        clicked=true;
        return btn;
    }

    //IF BUTTON CELL VALUE CHNAGES,IF CLICKED THAT IS
    @Override
    public Object getCellEditorValue() {
        if(clicked)
        {
            JOptionPane.showMessageDialog(btn, lbl+" Clicked");
        }
        //SET IT TO FALSE NOW THAT ITS CLICKED
        clicked=false;
        return new String(lbl);
    }

    @Override
    public boolean stopCellEditing() {

         //SET CLICKED TO FALSE FIRST
        clicked=false;
        return super.stopCellEditing();
    }

    @Override
    protected void fireEditingStopped() {
        // TODO Auto-generated method stub
        super.fireEditingStopped();
    }
}

ButtonRenderer.java

public class ButtonRenderer extends JButton implements  TableCellRenderer
{
    //CONSTRUCTOR
    public ButtonRenderer() {
        //SET BUTTON PROPERTIES
        setOpaque(true);
    }
    @Override
    public Component getTableCellRendererComponent(JTable table, Object obj,
        boolean selected, boolean focused, int row, int col) {

        //SET PASSED OBJECT AS BUTTON TEXT
        setText((obj==null) ? "":obj.toString());

        return this;
    }
}

在 JPanel 构造函数内，我需要在 swing 中添加一行已添加的表格调色板。

public samplePanel(){
    table.addRow(new Object[] {o.get(0), o.get(1), o.get(2), o.get(3), o.get(4), "DELETE"});
    table.getColumn("Action").setCellRenderer(new ButtonRenderer());
    table.getColumn("Action").setCellEditor(new ButtonEditor(new JTextField()));
}

我只是想获取单击删除按钮的行的数据，但我不知道该怎么做，因为我是渲染器和编辑器的新手。

JTable 有一个鼠标点击监听器。 还有一个“ListSelectionListener”，但这种方式要容易得多（对于简单的情况）

我就是这样做的：

jTable1.addMouseListener(new MouseAdapter() {
  @Override
  public void mouseClicked(MouseEvent e) {
    rowClicked(e);
  }
});
