Tizen supports development with Web technologies and Native (Tizen Mobile). The Native API is C (thus usable from both C and C++), with many features. The UI toolkit that controls main-loop, event handling, UI and rendering is EFL, and knowing what is available and how best to use it can save you a lot of time and energy going the wrong direction. This will cover a quick overview of how this toolkit works and how best to achieve some common results whilst avoiding pitfalls. Questions will also be answered for any developers presenting any.
