jSplitPane 具体场景使用

使用了一个JSplitPane，左边是导航面板，有按钮，右边是空的面板，击左边的导航按钮，右边就显示响应的面板窗口。

效果实现的具体方法是：（1）点击左侧按监听事件启动

				     （2）监听方法调用写好的改变面板显示的方法

				     （3）简单方法实例如下：

					public void first(){
						 	  JPanel first = new JPanel();
							first.setBackground(Color.black);
							jsp.remove(1);
							repaint();
							jsp.setRightComponent(first);
							validate();
					}           

说明：首先要删除掉JSplitPane面板中右侧的面板，调用repaint（）方法后，再将要展示的面板添加到JSplitPane的右侧，再调用validate（）方法。
