Tizen Native API
5.5
|
API for widget viewer (widget screen, home screen, ...).
#include <widget_viewer_evas.h>
Tizen Platform supports development of Widget Viewer Application. Many kinds of widgets can be installed on the Tizen Platform enhanced devices. Also it could be used by user via some kinds of viewer applications. This document will show you what kinds of APIs are existing and how to use them. First of all, the Tizen Platform uses the EFL as a core UIFW. So this API set is also based on the EFL.
