|
|
* Transit (see Warning below) is designed to set the various effects for the
|
|
* Evas_Object such like translation, rotation, etc. For using Effects, Create
|
|
* transit and insert effects which are interesting.
|
|
* Once effects are inserted into transit, transit will manage those effects.
|
|
* (ex deleting).
|
|
*
|
|
* Example:
|
|
* @code
|
|
* Elm_Transit *trans = elm_transit_add();
|
|
* elm_transit_object_add(trans, obj);
|
|
* void *effect_context = elm_transit_effect_translation_context_new(0.0, 0.0,
|
|
* 280.0, 280.0);
|
|
* elm_transit_effect_add(transit,
|
|
* elm_transit_effect_translation_op, effect_context,
|
|
* elm_transit_effect_translation_context_free);
|
|
* elm_transit_duration_set(transit, 5);
|
|
* elm_transit_auto_reverse_set(transit, EINA_TRUE);
|
|
* elm_transit_tween_mode_set(transit, ELM_TRANSIT_TWEEN_MODE_DECELERATE);
|
|
* elm_transit_repeat_times_set(transit, -1);
|
|
* @endcode
|
|
*
|
|
* @warning We strongly recomend to use elm_transit just when edje can not do
|
|
* the trick. Edje has more advantage than Elm_Transit, it has more flexibility and
|
|
* animations can be manipulated inside the theme.
