Q:

Java Swing JPanel slide up animation?

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)
I am not so good with swing, how can I do that ?
Thank you very much !
Regards

A:

SwingX comes with a JXCollapsiblePanel which might be helpful. Its demo shows it in action (as taskPanes) at the left - that's the part for choosing the demos.
