Refresh GLAnimJPanel


I would like to know how I can refresh a GLAnimJPanel inserted in JPanel.

For example: I draw a small scene and the user wants to drag with the mouse on the scene… i would like the draw to appear. I did it with a GLAnimCanvas and it worked. But now that I used a GJAnimJPanel I can’t refresh the screen…

Do you know how to do it
Thanks a lot…
