Is there any documentation on the user interface level API's for series 60. I am trying to develop applications in C++, and have been stomped by the fact that I couldn't find a single document that coherently lists the basic development issues like 1) What are the widgets available 2) Layout managers 3) Graphical and windowing primitives.
Also, I would like to know how Series 60 differs from the standard Symbian distribution. There are plenty of documents that gloss over this at a very high level, but I haven't come across a single one which provides me more indepth architecture documentation.
Any information is appreciated.
