[Qt-jambi-interest] resize inner borders of GridLayout?

[Dawid Sip]

Hi
Im creating a GridLayout and set it as the centralWidget. I then perform 
an action which creates a dockWidget with a GraphicsView inside and adds 
this dockWidget to the respecively first row/first collumn, on the next 
call to that action - first row/second collumn, and on the third call - 
second row/span over two collumns. Im getting something like this:
[] | []
-----
[___]

where [] corresopnds to dockWidet and | and ---- to the borders. Now I 
wish to be able to resize the inner borders freely. I looked for a 
method which sets such behavior but it seems that there is non. Is it 
possible to achieve this behavior with this widget composition?
