Tizen Native API
Widget Viewer

API for widget viewer (widget screen, home screen, ...)

Required Header

#include <widget_viewer_evas.h>

Overview

Tizen Platform supports development of Widget Viewer Application. Many kinds of widgets can be installed to 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 exist and how to use them.

First of all, the Tizen Platform uses the EFL as a core UIFW. So this API set also based on the EFL.
