Suggestions in giving to my application a cool look

[SkripT]

Thanks a lot Glitch, I will try it and I will comment the results....

EDIT: I think that I dont' understand how to fix the contents margins:

...If setContents marginis set correctly the toplevel layout of this book class will only allocate space defint by the readctangle "Widget1" + "Widget2" + Space in the middle. You can use two widgets for layout in your implementation, but since those blank container QWidgets will get snapshots for thier backgrounds that is a simple implementation detail.

Could you explain me it again, please?
