Is there a way to refresh?

Question

Is there a way to refresh a window through a method? I've been using setVisible(boolean) to do so, but I was hoping that there was another way to do so.

In the future, Swing related questions should be posted in the Swing forum.
The code you posted is of little use since it uses custom classes so we can't see the behaviour of your code.
In general if you add a component to a Container at run time then you just use
container.revalidate()
This will invoke the LayoutManager and repaint the components in the container based on the new layout.
