QFileIconProvider and QFileDialog

Hello, I would like to ask if these two can be used together so as to have a normal file dialog with a picture preview on the side, nothing more but also nothing less.

I've read the documentation and it sounded strange for me as I didn't eeven get what QFileIconProvider does :P

Thanks for any reply :D

Well, at least somebody with a good tip on how to start creating such a custom dialog from my program :/ ?

Or this is not at all possible with Qt?
