// SfxFrame is a management class for windows and their content.
// A SfxApplication represent a hierarchy of SfxFrames, with which the actual
// content in the derived classes is defined. The base class SfxFrame
// implements two aspects of frames: naming and control of its lifespan.
// Inside a frame hierarchy the parent frame always controls the lifespan of
// its child frames, even though they usually are not even produced by the
// parent. By calling DoCloser() on any frame in the hierarchy,
// a part of the "framework" can be removed, where frames unsubscribe
// from their parent frames.
