关于在jtable中放入jbutton的另外的一个问题,欢迎大家来讨论，分还可以加200分？

Question

你是想在编辑的时候响应button事件还是显示的时候？你是怎样实现放入jbutton的？
你最好用重写cellrenderer或则celleditor来实现你要的功能，这样应该没问题，
我做过

Answer 1

我给出代码！
 //changeButtonRender
    private class ChangeButtonRenderer extends JButton implements TableCellRenderer{
        JButton button=new JButton();
        public ChangeButtonRenderer(){
            button.setBorder(BorderFactory.createLineBorder(Color.black));
            setOpaque(true);
        }
        public Component getTableCellRendererComponent(
                JTable t,Object value,
                boolean isSelected,
                boolean hasFocus,
                int row,int col){
            button.setText(dataModel.getValueAt(row,3).toString());
            return button;
        }
    }
    //ChangeButtonEditor
 public class ChangeButtonEditor extends DefaultCellEditor {
     protected JButton button;
     private int hererow;     public ChangeButtonEditor(JCheckBox checkBox) {
         super(checkBox);
         button = new JButton();
         button.setBorder(BorderFactory.createLineBorder(Color.black));
         button.setOpaque(true);
         button.addActionListener(new ActionListener() {
             public void actionPerformed(ActionEvent e) {
                 dataModel.setValueAt((Integer.parseInt(dataModel.getValueAt(hererow,3).toString()) +1)%3+"",hererow,3);
                 button.setText(dataModel.getValueAt(hererow,3).toString());
             }
         });
     }     public Component getTableCellEditorComponent(JTable table, Object value,
             boolean isSelected, int row, int column) {
         hererow=row;
         button.setText(dataModel.getValueAt(hererow,3).toString());
         return button;
     }     public Object getCellEditorValue() {
         return null ;
     }     public boolean stopCellEditing() {
         return super.stopCellEditing();
     }     protected void fireEditingStopped() {     }
    }

Answer 2

     protected void fireEditingStopped() {         super.fireEditingStopped();
     }

Answer 3

public Object getCellEditorValue() {
         return null ;
     }
这个方法好像也有问题，当取消编辑状态时，好像jtable是调用这个方法获取修改后的值的。
