Don't forget to call validate() after a remove/add.
The GUI is updated both using validate() or updateUI(). Which is
difference?
The updateUI() call is normally needed only if you're changing the UI
delegates of components - for example, if you switch Look and Feels at
run time.
A validate() call rarely helps when used by itself. (It performs a
validation only if swing thinks that the container's layout is in an
invalid state). You need to first call invalidate() followed by a
validate() for forcing a validation.
For Swing components, the best method to use after you've changed the
contents of a container is the revalidate() call (followed by a
repaint() ). However this method is not available in AWT
containers, so you'd have to use an invalidate() / validate() sequence
there.
