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:
