[Qt-interest] How to apply scroll bars in mdi files.

[Sujan Dasmahapatra]

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.

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.
