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:

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

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.

Function Documentation

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.

Since :: 2.3

Eina_Bool elm_transit_auto_reverse_get ( const Elm_Transit * transit )

Get if the auto reverse is on.

See also:: elm_transit_auto_reverse_set()

Parameters:

transit The transit object.

Since :: 2.3

void elm_transit_auto_reverse_set	(	Elm_Transit *	transit,
		Eina_Bool	reverse
	)

Set reverse effect automatically.

If auto reverse is set, after running the effects with the progress parameter from 0 to 1, it will call the effects again with the progress from 1 to 0. The transit will last for a time equal to (2 * duration * repeat), where the duration was set with the function elm_transit_add and the repeat with the function elm_transit_repeat_times_set().

Parameters:

transit	The transit object.
reverse	`EINA_TRUE` means the auto_reverse is on.

Since :: 2.3

void elm_transit_chain_transit_add	(	Elm_Transit *	transit,
		Elm_Transit *	chain_transit
	)

Makes the chain relationship between two transits.

Note:: transit can not be NULL. Transit would have multiple chain transits.; chain_transit can not be NULL. Chain transits could be chained to the only one transit.

Parameters:

transit	The transit object.
chain_transit	The chain transit object. This transit will be operated after transit is done.

This function adds chain_transit transition to a chain after the transit, and will be started as soon as transit ends. See elm_transit - Chained transitions. for a full example.

Since :: 2.3

void elm_transit_chain_transit_del	(	Elm_Transit *	transit,
		Elm_Transit *	chain_transit
	)

Cut off the chain relationship between two transits.

Note:: transit can not be NULL. Transit would have the chain relationship with chain transit.; chain_transit can not be NULL. Chain transits should be chained to the transit.

Parameters:

transit	The transit object.
chain_transit	The chain transit object.

This function remove the chain_transit transition from the transit.

Since :: 2.3

Eina_List* elm_transit_chain_transits_get ( const Elm_Transit * transit )

Get the current chain transit list.

Note:: transit can not be NULL.

Parameters:

transit The transit object.

Returns:: chain transit list.

Since :: 2.3

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.

Since :: 2.3

void elm_transit_del_cb_set	(	Elm_Transit *	transit,
		Elm_Transit_Del_Cb	cb,
		void *	data
	)

Set the user-callback function when the transit is deleted.

Note:: Using this function twice will overwrite the first function set.; the transit object will be deleted after call cb function.

Parameters:

transit	The transit object.
cb	Callback function pointer. This function will be called before the deletion of the transit.
data	Callback function user data. It is the `op` parameter.

Since :: 2.3

double elm_transit_duration_get ( const Elm_Transit * transit )

Get the transit animation time

Note:: transit can not be NULL

Parameters:

transit The transit object.

Returns:: The transit animation time.

		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.

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`.

int elm_transit_repeat_times_get ( const Elm_Transit * transit )

Get the transit repeat count.

See also:: elm_transit_repeat_times_set()

Parameters:

transit The Transit object.

Returns:: The repeat count. If transit is NULL 0 is returned

Since :: 2.3

void elm_transit_repeat_times_set	(	Elm_Transit *	transit,
		int	repeat
	)

Set the transit repeat count. Effect will be repeated by repeat count.

This function sets the number of repetition the transit will run after the first one, i.e., if repeat is 1, the transit will run 2 times. If the repeat is a negative number, it will repeat infinite times.

Note:: If this function is called during the transit execution, the transit will run repeat times, ignoring the times it already performed.

Parameters:

transit	The transit object
repeat	Repeat count

Eina_Bool elm_transit_smooth_get ( const Elm_Transit * transit )

Get the smooth scaling for transit map rendering

This gets smooth scaling for transit map rendering.

Parameters:

transit The transit object

Returns:: EINA_TRUE if the smooth is enabled, EINA_FALSE otherwise.

void elm_transit_smooth_set	(	Elm_Transit *	transit,
		Eina_Bool	enabled
	)

Set the smooth effect for a transit.

Parameters:

transit	The transit object
enabled	enable or disable smooth map rendering

This sets smoothing for transit map rendering. If the object added in a transit is a type that has its own smoothing settings, then both the smooth settings for this object and the map must be turned off. By default smooth maps are enabled.
