Notify

The notify UI component displays a container in a particular region of the parent object. It can receive some content, and become automatically hidden after a certain amount of time. The popup component is very similar to the notify component, but supports many common layouts. For more information, see the Notify API.

This feature is supported in mobile applications only.

Basic Usage

To use a notify component in your application:

1. Add a notify component with the elm_notify_add() function:

   Evas_Object *notify;
   
   notify = elm_notify_add(parent);
   

2. Fill the layout:

   • Add an object to fill the layout:

     Evas_Object *label = elm_label_add(parent);
     

   • Set an object to the notify component with the elm_object_content_set() function:

     elm_object_content_set(notify, label);
     

3. Register the callback functions.

   The following example shows how to define and register a callback for the timeout signal:

   evas_object_smart_callback_add(notify, "timeout", timeout_cb, data);
   
   void
   timeout_cb(void *data, Evas_Object *obj, void *event_info)
   {
       dlog_print(DLOG_INFO, LOG_TAG, "Notify timeout");
   }
   

The following example shows a simple use case of the notify component.

Example: Notify use case

Evas_Object *win;
Evas_Object *conf;
Evas_Object *notify;
Evas_Object *label;

/* Starting right after the basic EFL UI layout code */
/* (win - conformant) */

/* Add a notify component to contain a label to the conformant */
notify = elm_notify_add(conf);
elm_notify_align_set(notify, ELM_NOTIFY_ALIGN_FILL, 1.0);
elm_notify_timeout_set(notify, 5.0);

/* Add a label to notify */
label = elm_label_add(notify);
elm_object_test_set(label, "A label in notify");
evas_object_show(label);
elm_object_content_set(notify, label);

evas_object_show(notify);

Features

You can use the align and timeout features with the notify component:

• Align

  Using the elm_notify_align_set() function, you can set the notify component alignment.

  The second and third parameters have a value between 0.0 and 1.0, meaning the alignment of the notify component’s position within the parent window. The ELM_NOTIFY_ALIGN_FILL value can be used to fill the notify component in each axis direction.

  To align the notify object to the bottom center of the parent object:

  elm_notify_align_set(notify, 0.5, 1.0);
  

• Timeout

  The notify component can set a timeout interval, after which the notify component is hidden.

  To set the timeout interval to 5 seconds:

  elm_notify_timeout_set(notify, 5.0);
  

Callbacks

You can register callback functions connected to the following signals for a notify object.

The signal list in the API reference can be more extensive, but only the above signals are actually supported in Tizen.
