@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 every time a component will detached from a frame
we store its current position and size to the configuration. Every time a new component is
attached to a frame first time(!) we restore this information again.
@base OWeakObject
implements ref counting for this class.
