[maemo-developers] Resources for learning Qt on Mameo5 Fremantle

[From: Jonathan Wilson]

I am looking for resources related to learning Qt on Maemo5 Fremantle.
More specifically I am trying to understand the workings of this app: (and 
add some new features to it such as a one-step undo for when you press the 
wrong block by mistake)
http://maemo.org/packages/view/skidstone/

I have a copy of a book titled "C++ GUI Programming with Qt 4 Second 
Edition", will the information in that book be of any use in understanding 
whatever version of QT Maemo5 has?
Where can I find tutorials and things dealing with mobile-specific stuff 
like touch events?
