Closing all possible GUI related elements

Is there a way to close开发者_StackOverflow社区 (or get a handle to) all possible windows, dialogs, prompts, etc. created with Java?

I have an app that creates GUI elements here and there (while it automatically runs tests and such) and sometimes it leaves these elements open. I would like to be able to close all those things from one place.

Edit. I am teh retarded xP

This will give you every Window (parentclass of Frame, Dialog, JWindow, Grandparent of JFrame, JDialog, etc).

Well this gets all of the Frames that are open. I don't think there is an equivalent for Dialog, but there is the getOwnedWindows() method on Window. I don't know who owns dialogs constructed with a null Frame argument.

Set a collection and then make it close each element.

EDIT:

Ok, here is an exemple, I don't know if ArrayList is the best choice here :

class Main{
    public static final ArrayList<Window> containers = new ArrayList<Window>();

    public static final void closeEverything(){
        ListIterator<Window> list = containers.getListIterator();
        while(list.hasNext()){
              list.next().dispose();
        }
    }
}

Then, when you create a Window that you wish to be disposable, you just have to add :

Main.containers.add(this);

in the constructor.
