Qt QSplitter stretch widget out of container

Hello Everyone,

I am trying something different with QSplitter, may be there is other way to do that., but i am trying to find out that way.
What i am doing is :
I want a QScrollArea contain two widgets split vertically with each other with QSplitter.
Now if i stretch the widget via QSplitter then after going beyond the stretch it start showing sliders.

But my current work is something different than my need.
what it doing is it just go to its maximum stretch limit and thats it. it doesnot allow me to stretch beyond the limit.

Any idea how to do that possible?
