repaint?
 

I have a window and after an event I rebuild a container that is in the window. currently I empty the container and then re-add the elements to it so get me new container. The container is the windows content pane. When I make changes in the container they do not show up. Can anymore offer me a bit of help? I can post my code if you need me to.

And btw, repaint() is not doing anything. I know stuff is happening because I can hide the window and show it and the new one is correct, but I then have 2 windows.

Try calling validate() on your container.
