Is there any Qt4 implementation for auto-hiding tool windows and the window-docking mechanisms introduced in Visual Studio 2005?

So that everybody knows what I mean, here are a few links:
- Codejock DockingPane (implementation for MFC)

- "Tool Window Docking" (msdn blog)

Will such features be integrated in forthcoming versions of Qt?

Hope to get valuable suggestions.
