Flip

The flip UI component is used for a transition effect, which can hold 2 Evas_Objects and flip between them using several predefined animations. For more information, see the Flip API.

This feature is optional.

Basic Usage

To use a flip component in your application:

1. Add a flip with the elm_flip_add() function:

   Evas_Object *flip;
   
   flip = elm_flip_add(parent);
   

2. Add content to the flip using the elm_object_part_content_set() function. Use the front and back part names to define the 2 Evas_Objects used as content:

   elm_object_part_content_set(flip, "front", content1);
   elm_object_part_content_set(flip, "back", content2);
   

3. Run a flip animation using the elm_flip_go() function. The ELM_FLIP_CUBE_UP animation mode flips up the front content object as if it was on a side of a cube, letting the down facing side of the cube appear with the back content object.

elm_flip_go(flip, ELM_FLIP_CUBE_UP);

4. Register the callback functions.

   The following example shows how to define and register a callback for the animate,begin signal.

   evas_object_smart_callback_add(entry, "animate,begin", anim_start_cb, data);
   
   void
   anim_start_cb(void *data, Evas_Object *obj, void *event_info)
   {
       dlog_print(DLOG_INFO, LOG_TAG, "Animation starts\n");
   }
   

User Interactions

By default, the user cannot interact with the flip. You can set the interaction to be possible, but you have to define some interaction settings as well.

To set interaction settings to enable the user to interact with the flip:

• Select which animation appears on the interaction.

  To set the rotation animation:

  elm_flip_interaction_set(flip, ELM_FLIP_INTERACTION_ROTATE);
  

• Select which interaction directions are enabled.

  To enable the right and left directions only:

  elm_flip_interaction_direction_enabled_set(flip, ELM_FLIP_DIRECTION_LEFT, EINA_TRUE);
  elm_flip_interaction_direction_enabled_set(flip, ELM_FLIP_DIRECTION_RIGHT, EINA_TRUE);
  

• Set the amount of the flip that is sensitive to user interaction.

  To set the entire flip sensitive (to make the flip easy to interact with), use the amount 1:

  elm_flip_interaction_direction_hitsize_set(flip, ELM_FLIP_DIRECTION_LEFT, 1);
  elm_flip_interaction_direction_hitsize_set(flip, ELM_FLIP_DIRECTION_RIGHT, 1);
  

Callbacks

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

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