40 class WatchApplication;
45 * @brief A WatchApplication class object should be created by every watch application
46 * that wishes to use Dali.
48 * It provides a means for initialising the resources required by the Dali::Core.
49 * Like Application class, the WatchApplication class manages Tizen watch application life cycle.
51 * The WatchApplication class emits additional signals which are availalble only in the watch application
52 * (TimeTick, AmbientTick, AmbientChanged)
54 * This feature is supported in wearable applications only.
56 * WatchApplication should follow the example below:
59 * class ExampleController: public ConnectionTracker
62 * ExampleController( WatchApplication& application )
63 * : mApplication( application )
65 * mApplication.InitSignal().Connect( this, &ExampleController::Create );
68 * void Create( Application& application )
70 * // Create Dali components...
74 * WatchApplication& mApplication;
77 * int DALI_EXPORT_API main (int argc, char **argv)
79 * WatchApplication app = WatchApplication::New(&argc, &argv);
80 * ExampleController example( app );
85 * If required, you can also connect class member functions to a signal:
89 * app.ResumeSignal().Connect(&app, &MyApplication::Resume);
92 * When the above options are found, they are stripped from argv, and argc is updated appropriately.

163 * @brief This signal is emitted at every second
164 * A callback of the following type may be connected:
166 * void YourCallbackName(Application& application, WatchTimeSignal &time);
168 * time(watch time handle) will not be available after returning this callback. It will be freed by the framework.

180 * time(watch time handle) will not be available after returning this callback. It will be freed by the framework.
182 * @remarks http://tizen.org/privilege/alarm.set privilege is needed to receive ambient ticks at each minute.
183 * The AmbientTickSignal() will be ignored if your app doesn't have the privilege
