    @short          listener for closing document frames to make her window state persistent
    @descr          It's a feature of our office. If a document window was created by ourself (and not from
                    any external process e.g. the office bean) we save and restore the window state of it
                    corresponding to the document service factory. That means: one instance of this class will be
                    a listener on one frame which container window was created by ourself.
                    We listen for frame action events and everytimes a component will deattached from a frame
                    we store its current position and size to the configuration. Everytimes a new component is
                    attached to a frame first time(!) we restore this informations again.

    @base           ThreadHelpBase
                        guarantee right initialized lock member during startup of instances of this class.

    @base           OWeakObject
                        implements ref counting for this class.
