博为峰小博老师：

JLayeredPane面板主要是为JFC、Swing容器添加深度，它允许组件在必要的时候相互重叠。其实JLayeredPane面板将面板深度范围分成多个不同的层，将组件放入不同的层内，这样可以保证组件能够正确的重叠，而不必为具体的深度编号。

实例代码如下所示:

publicclassBWFextendsJFrameimplementsActionListener{

publicstaticintWIDTH=400;

publicstaticintHEIGHT=300;

publicstaticJLayeredPanelp;

publicstaticJButtonbutton1;

publicstaticJButtonbutton2;

publicBwfJButton() {

JFrame jf=newJFrame("博为峰教育");

jf.setSize(WIDTH,HEIGHT);

jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

lp=newJLayeredPane();

button1=newJButton("确定");

button2=newJButton("取消");

button1.addActionListener(this);

button2.addActionListener(this);

lp.add(button1,newInteger(200));

lp.add(button2,newInteger(300));

button1.setBounds(newRectangle(100,100,100,100));

button1.setVisible(true);

button2.setBounds(newRectangle(50,50,100,100));

button2.setVisible(true);

jf.setContentPane(lp);

jf.setVisible(true);

}

publicstaticvoidmain(String args[]){

newBwfJButton();

}

publicvoidactionPerformed(ActionEvent e) {

if(e.getActionCommand().equals("确定")){

lp.setLayer(button1, 300);

lp.setLayer(button2, 200);

}elseif(e.getActionCommand().equals("取消")){

lp.setLayer(button1, 200);

lp.setLayer(button2, 300);

}

}

}
