Hi!

I'm Jean and I'm new to Qt, but am professional c++ developer for many years.
I have a new project in which I have to create a good flowing using interface. I have opted for Qt.

I need to create a UI similar to Guitar Pro 6:
"http://www.guitar-pro.com/en/index.php?pg=product"
I am mainly interested in the "Soundboard" on the given page (you can see/search it there to see what I mean. I would like to know which Qt class I need to use to create similar red/yellow/green/blue controls and the stacking components on their left side. Guitar, bass, drums...etc...).
(Note, colour is not the issue, but the actual control :-))

I'm already thinking of using QGraphicsView/Scene&Item.
- Is this a good way forward?
- Any more advice on how to achieve this kind of overall UI is appreciated.

Many thanks for your help in advance.

Best regards,

Jean
