I've created a widget with contents of 3 QGroupbox, I am trying to place and align them respectively with QGridLayout. Strange behaviour of QGroupboxsmakes this question.
What looks like currently.
As shown above figure when Qwidget screen stretchs in and out, Every group overlap each other and by outstretching replaces strangely and unwanted.
What I want to be....
By stretching in want all groups keeping its own position Fixed and scrollbar would appear instead.
The code is:

The problem is simple, the groupboxes that are inside ClassA, ClassB and ClassC are just children and therefore the
minimunSizeHint()of ClassA, ClassB and ClassC is(0, 0). For example, we show classA:So there are 2 solutions:
1. The first is to establish a layout for ClassA, ClassB and ClassC classes, for example:
Complete code:
2. Or classA, class and class are inherited from QGroubBox, for this you can, for example, do the following:
