Please somebody look at this issue....
Re: Scroll bars in scroll area not comming in scroll area
Remove the grid layout. Set the scroll area layout to grid with the starting push button and edit widget in that grid. Set the scrollBarWidgetContents layoutSizeConstraint to setFixedSize. Add new widgets with ui->scrollBarWidgetContents->layout()->addWidget().
If you want the scroll bars visible at all times then you should set that... it isn't in your example.
