Problem with JScrollPane while Scrolling

  Asked By: Kristopher    Date: Oct 07    Category: Java    Views: 1162

I have a problem. I have a JPanel which has some JAVA2D graphics on it.
I placed this panel into a JScrollPane.
If I scroll the JScrollpane, the Jpanel is not repainted automatically. The
Java2D graphics on the JPanel gets smeared.

Any ideas how I can overcome this problem? I thougt that, maybe there is a
listener, which listens to this scrolling action. But I couldn't find anything.

You can possibly adapt the MouseMotionListener, to track the
scrolling action. Everytime a mouse event occurs, you can check
whether JScrollPane's scrollbars' value has changed. If some
scrollbar value changes then repaint the JPanel.
