Prevent Java from repainting the content of a JPanel while updating

I have a JPanel which contains a lot of child components. While updating\adding new components to the parent JPanel I'd like to prevent it from repainting, how can this achieved?

Try RepaintManager.currentManager(component).markCompletelyClean(component). It will prevent the component from repainting. You might need to do this after each time you add new components.

you could try by using setIgnoreRepaint(boolean value) but it's a typical swing feature that can or cannot work (mainly because it depends from AWT so you never know).

Otherwise you could override the paint method by using a flag that simply makes the methor return without calling super.paint(). (actually overriding paintComponent should be the right choice)
