Jtable单元格编辑状态添加鼠标右键菜单

核心：重写JTextField，为自己的JTextField实现右键菜单，然后制定单元格默认编辑器为自定义的JTextField。

public class MyJTextField extends JTextField {

	private static final long serialVersionUID = 1L;
	private JPopupMenu jPopupMenu = new JPopupMenu();
	private JMenuItem copy = new JMenuItem("复制");
	private JMenuItem paste = new JMenuItem("粘贴");
	private JMenuItem cut = new JMenuItem("剪切");
    
    MyJTextField myself = this;
	
	public MyJTextField(){
		this.addMouseListener(new MouseAdapter(){
			public void mousePressed(MouseEvent arg0) {
				if(arg0.getButton()==3){
					if(myself.isEnabled()){//如果当前组件处于不可用状态，则不弹出右键菜单
					
						jPopupMenu.removeAll();
						if(!myself.isEditable()){
							jPopupMenu.add(copy);
						}else{
							jPopupMenu.add(copy);
							jPopupMenu.add(paste);
							jPopupMenu.add(cut);
						}
						jPopupMenu.show(arg0.getComponent(), arg0.getX(), arg0.getY());		
					}	
				}
			}
        });
		
		jPopupMenu.add(copy);
		jPopupMenu.add(paste);
		jPopupMenu.add(cut);
        
		copy.setIcon(ImageIcons.copy_gif);
		copy.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent arg0) {
				myself.copy();
			}
		});
	    paste.setIcon(ImageIcons.paste_png);
        paste.addActionListener(new ActionListener(){
			public void actionPerformed(ActionEvent arg0) {
				myself.paste();		
			}   	
        });
        cut.setIcon(ImageIcons.cut_png);
        cut.addActionListener(new ActionListener(){
			public void actionPerformed(ActionEvent arg0) {
				myself.cut();		
			}   	
        });    
	}	
}

 

//Jtable单元格的默认文本编辑器
    DefaultCellEditor objectDefaultCellEditor = new DefaultCellEditor(new MyJTextField());

JTable jtable = new JTable(myTableModel);
     jtable.setDefaultEditor(Object.class,objectDefaultCellEditor);//为Object类型指定默认编辑器
