如何在swing 中画矩形,并且实现其action.

[hcgerard]

1,我想在swing的jpanel上面画矩形.但是具体画多少,需要看传递的参数,请问如何去画;
2,当我的鼠标进入到相应的矩形范围的时候，就能够点击，点击之后 再弹出 joption.

请问 怎么给你们加分啊

如何去动态的定义矩形啊
如这样 我把这个作为一个class,
然后调用它, 我传递一个参数k,
然后画k个矩形,是平行的.

问题:1,如何去画平行k个的矩形,

可以直接使用JTable。
参数大概是个2维数组吧，按照数组的长度生成对应的table，并且把数据设置进去。
在tableCell里增加clicked事件，触发JOption.show*Dialog()

简单写了一个

    private Shape shape = null;
    
    /** Creates new form DrawPanel */
    public DrawPanel() {
        initComponents();
    }
    
    /** This method is called from within the constructor to
     * initialize the form.

        this.shape = shape;
    }
    
    
    // Variables declaration - do not modify

            Graphics2D g2d = (Graphics2D)g;
            g2d.draw(getShape());

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        DrawPanel drawPanel = new DrawPanel();
        drawPanel.setShape(new Rectangle(20, 20, 100, 100));
        frame.add(drawPanel, BorderLayout.CENTER);
        
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

封装定义一个矩形类，实现绘制自己、判断点是否在框里面两个方法。
行否？

用底层的graphics2D来画，提供最大的灵活性
