Simple Java Questions about JPanels
When I changed my code to use a JPanel instead of a regular panel, my button keeps disappearing when I resize the window. It didn't do that when I used just a regular panel...

any ideas why?

Java Code:
Original - Java Code 
  1.  
  2.  public void start()
  3.     {
  4.         JButton refButton = new JButton("Refresh!!");
  5.    
  6.         JPanel mainPanel = new JPanel(new FlowLayout());
  7.     
  8.         
  9.         mainPanel.add(refButton);
  10.        
  11.         
  12.         
  13.         getContentPane().add(mainPanel, BorderLayout.NORTH);
  14.         
  15.         
  16.     }


Guess I should add something to that. The button doesn't show up until the panel is clicked, at least in FF.

when does this method get called. If it get's called at any point after the frame is displayed then that's probably the problem.

It's called in the start method. Maybe I should move it to the init method?
