title: Java Swing JPanel slide up animation?
body: <p><img src="https://i.stack.imgur.com/f1Lvc.jpg" alt="enter image description here"></p>
  
  <p>I have this thing and when I click on the filter arrow (it should be a up arrow I know):
  - the form pannel above has to slide up slowly (and disapear)
  - the green panel has to be lifted up 
  - the bottom scrollpane has to slowly rise up its height (+the height of the form panel)</p>
  
  <p>I am not so good with swing, how can I do that ?</p>
  
  <p>Thank you very much !</p>
  
  <p>Regards</p>
