title: Dynamic adding JPanel to another JPanel in Java Swing
body: <p>I am very new for the java swing and so does java. I use netbeans' window's builder to design the GUI. I have a JPanel called orderListPanel which includes a JPanel called orderListRowPanel. Now, I got a list of JPanel and I want to insert these JPanels to the orderListPanel. </p>
  
  <p><a href="http://postimage.org/image/ex00whf69/" rel="nofollow">http://postimage.org/image/ex00whf69/</a><br>
  orderListPanel is in the middle and orderListRowPanel is just the same place like orderListPanel</p>
  
  <p><a href="http://postimage.org/image/dbrtn33sj/" rel="nofollow">http://postimage.org/image/dbrtn33sj/</a><br>
  right now I wanna insert many JPanels into orderListPanel and make it look like a list. The red squares are the components in side the JPanel.</p>
  
  <p>I try to use BorderLayout and when I use 
  foreach loop orderListPanel.add(List pList), I can't see any result inside the orderListPanel. Do anybody know how to solve it?</p>
