QDockWidget locations

[elcuco]

I am trying to convice a layout of 3 dockbars to be placed in a very specific way, and I am missing something.

I want to put the 3 docks on the borders of the window, and the 2 on the sides to be streched from the top to the bottom, and the 3rd on the middle between them.

What I can achieve is only that the bottom dock is spanned over the bottom of the window.

In the attached image the left is what I get, and rigth is what i want (the dock is floating for the screen shot). I saw that FullMetelCoder made this on edyuk, but I failed to find the exact code.
