[Qt-interest] how to add a scrollBar in QTabWidget

[Sujan Dasmahapatra]

I want to ask onething that this layout creation is not mandatory right ? If I have a complex set of controls then layout creation is not possible. Still my controls should pop up  in the pages.at(i) and I should be able to see them. Any comments,  Thanks sujan

Hi,

This is not a complete complete compilable example but anyway here is the source of your current problem:
you need to use layouts, try with my little modification in your code.

You might also want to go through http://doc.qt.nokia.com/4.7/widgets-tutorial.html 

Hope this helps
Samuel
