The purpose of this section is to explain how to use the features offered by the application framework when designing and implementing your application. Note that, for GUI-based applications, a strict division between the this section and the S60 UI section is difficult to draw. For example, this section covers resource file management, but there are also implications for the S60UI section, which are covered there . For a full picture, read the S60 UI section in parallel to the application framework section.
