You create a widget of QGraphicsView and  on that view u draw whatever u 
want to draw automatically when ur objects exceed scroll bars will appear 
vertical as well as horizontal.set the parent for this graphicsview as ur 
mdi subwindow.
 
Kind regards,

Hi John, 

Thank you for the response. But I still have problem in resolving my 
issue. 
if I paint on MDI child window or subwindow and if the painting exceeds 
the subwindow size. 
For Eg: I painted a line in the subwindow and if the size of line exceeds 
the size of MDI subwindow then I expect a Horizontal scroll bar or 
Vertical scroll bar based on the area painted, but I am not getting any 
such scroll bar.Instead I need to use mouse pointer to increase the size 
of subwindow and see the diagram. 

what I have used is the MDI subwindow is of type widget and it is 
inherited by class QScrollArea and MDI window is of type MainWindow. 

Can you please suggest me how can i implement this with some example? 

Thank you in advance.

You must mean mdi windows, not files. If you want scrollbars in mdi 
subwindows, use widgets that have scrollbars as subwindows.
