Detailed Description

Transit is designed to apply various animated transition effects to Evas_Object, such like translation, rotation, etc.

For using these effects, create an Transit and add the desired transition effects.

Once the effects are added into transit, they will be automatically managed (their callback will be called for the set duration and they will be deleted upon completion).

Example:

Elm_Transit *trans = elm_transit_add();
elm_transit_object_add(trans, obj);
elm_transit_effect_translation_add(trans, 0, 0, 280, 280
elm_transit_duration_set(transit, 1);
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, 3);

Some transition effects are used to change the properties of objects. They are:

• elm_transit_effect_translation_add
• elm_transit_effect_color_add
• elm_transit_effect_rotation_add
• elm_transit_effect_wipe_add
• elm_transit_effect_zoom_add
• elm_transit_effect_resizing_add

Other transition effects are used to make one object disappear and another object appear on its place. These effects are:

• elm_transit_effect_flip_add
• elm_transit_effect_resizable_flip_add
• elm_transit_effect_fade_add
• elm_transit_effect_blend_add

It's also possible to make a transition chain with elm_transit_chain_transit_add.

Warning

We strongly recommend to use elm_transit just when edje can not do the trick. Edje is better at handling transitions than Elm_Transit. Edje has more flexibility and animations can be manipulated inside the theme.

List of examples:

• elm_transit - Basic transit usage.
• elm_transit - Chained transitions.
• elm_transit - Combined effects and options.
• elm_transit - Combined effects over two objects.

Function Documentation

elm_transit_add()

Elm_Transit * elm_transit_add

(

void

)

Create new transit.

Note

It is not necessary to delete the transit object, it will be deleted at the end of its operation.

The transit will start playing when the program enters the main loop.

Returns

The transit object.

References EINA_MAGIC_SET, EINA_TRUE, ELM_TRANSIT_TWEEN_MODE_LINEAR, elm_transit_tween_mode_set(), and ERR.

elm_transit_del()

void elm_transit_del

(

Elm_Transit *

transit

)

Stops the animation and delete the transit object.

Call this function if you want to stop the animation before the transit time. Make sure the transit object is still alive with elm_transit_del_cb_set() function. All added effects will be deleted, calling its respective data_free_cb functions. The function set by elm_transit_del_cb_set() will be called.

See also

elm_transit_del_cb_set()

Parameters

transit

The transit object to be deleted.

References EINA_TRUE.

Referenced by elm_transit_effect_del(), and elm_transit_object_remove().

elm_transit_effect_add()

void elm_transit_effect_add	(	Elm_Transit *	transit,
		Elm_Transit_Effect_Transition_Cb	transition_cb,
		Elm_Transit_Effect *	effect,
		Elm_Transit_Effect_End_Cb	end_cb
	)

Add a new effect to the transit.

Note

The cb function and the data are the key to the effect. If you try to add an existing effect, nothing is done.

After the first addition of an effect to transit, if its effect list become empty again, the transit will be killed by elm_transit_del(transit) function.

Example:

Elm_Transit *transit = elm_transit_add();
elm_transit_effect_add(transit,
                       elm_transit_effect_blend_op,
                       elm_transit_effect_blend_context_new(),
                       elm_transit_effect_blend_context_free);

Parameters

transit	The transit object.
transition_cb	The operation function. It is called when the animation begins, it is the function that actually performs the animation. It is called with the data, transit and the time progression of the animation (a double value between 0.0 and 1.0).
effect	The context data of the effect.
end_cb	The function to free the context data, it will be called at the end of the effect, it must finalize the animation and free the data.

Warning

The transit will free the context data at the and of the transition with the data_free_cb function. Do not share the context data in between different transit objects.

elm_transit_effect_del()

void elm_transit_effect_del	(	Elm_Transit *	transit,
		Elm_Transit_Effect_Transition_Cb	transition_cb,
		Elm_Transit_Effect *	effect
	)

Delete an added effect.

This function will remove the effect from the transit, calling the data_free_cb to free the data.

See also

elm_transit_effect_add()

Note

If the effect is not found, nothing is done.

If the effect list become empty, this function will call elm_transit_del(transit), i.e., it will kill the transit.

Parameters

transit	The transit object.
transition_cb	The operation function.
effect	The context data of the effect.

References EINA_INLIST_FOREACH, EINA_SAFETY_ON_NULL_RETURN, EINA_TRUE, and elm_transit_del().

elm_transit_object_add()

void elm_transit_object_add	(	Elm_Transit *	transit,
		Evas_Object *	obj
	)

Add new object to apply the effects.

Note

After the first addition of an object to transit, if its object list become empty again, the transit will be killed by elm_transit_del(transit) function.

If the obj belongs to another transit, the obj will be removed from it and it will only belong to the other transit. If the old transit stays without objects, it will die.

When you add an object into the transit, its state from evas_object_pass_events_get(obj) is saved, and it is applied when the transit ends, if you change this state with evas_object_pass_events_set() after add the object, this state will change again when transit stops.

Parameters

transit	The transit object.
obj	Object to be animated.

Warning

It is not allowed to add a new object after transit begins.

References eina_list_append(), eina_list_data_find_list(), EINA_SAFETY_ON_NULL_RETURN, EINA_TRUE, evas_object_data_get(), evas_object_freeze_events_set(), and WRN.

elm_transit_object_remove()

void elm_transit_object_remove	(	Elm_Transit *	transit,
		Evas_Object *	obj
	)

Removes an added object from the transit.

Note

If the obj is not in the transit, nothing is done.

If the list become empty, this function will call elm_transit_del(transit), i.e., it will kill the transit.

Parameters

transit	The transit object.
obj	Object to be removed from transit.

Warning

It is not allowed to remove objects after transit begins.

References EINA_SAFETY_ON_NULL_RETURN, and elm_transit_del().
