• EverythingDisablerAndReenabler

  public EverythingDisablerAndReenabler(Container rootContainerForWhatShouldBeDisabled,
                                        Class<?>[] componentClassesToBeIgnored)

  Parameters:

  rootContainerForWhatShouldBeDisabled - NOT NULL! The Container whose components are to be recursively disabled. The container itself will not be disabled.

  componentClassesToBeIgnored - null or an array of classes (e.g. containing JLabel.class) that should be excluded from disabling. Adding a Container here does not affect the recursive process.

  Throws:

  IllegalArgumentException - if the container argument is null. In case someone wonders why I don't use NullPointerException here: Null can be a perfectly legal argument in other places, but here, it is not. If an argument does not check out, the choice of Exception, of course, is IllegalArgument, not NullPointer.
