Tizen Native API  5.5

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:

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.

The transit object.
Since :
2.3
Examples:
transit_example_01.c, transit_example_02.c, transit_example_03.c, and transit_example_04.c.

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().

Examples:
transit_example_03.c.
void elm_transit_chain_transit_add ( Elm_Transit transit,
Elm_Transit chain_transit 
)

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:
transitThe transit object.
chain_transitThe 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
Examples:
transit_example_02.c.
void elm_transit_chain_transit_del ( Elm_Transit transit,
Elm_Transit chain_transit 
)

chain transit list.
Since :
2.3

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:
transitThe transit object to be deleted.
Since :
2.3
void elm_transit_del_cb_set ( Elm_Transit transit,
Elm_Transit_Del_Cb  cb,

Using this function twice will overwrite the first function set.
the transit object will be deleted after call cb function.
Parameters:
transitThe transit object.
cbCallback function pointer. This function will be called before the deletion of the transit.
dataCallback function user data. It is the op parameter.

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:
transitThe transit object.
transition_cbThe 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).
effectThe context data of the effect.
end_cbThe 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.

double elm_transit_progress_value_get ( const Elm_Transit transit)

The value returned is a fraction (current time / total time). It represents the progression position relative to the total.

Note:
transit can not be NULL

int elm_transit_repeat_times_get ( const Elm_Transit transit)

Get the transit repeat count.

transitThe 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:
transitThe transit object
repeatRepeat count

Get the smooth scaling for transit map rendering

This gets smooth scaling for transit map rendering.

Parameters:
transitThe 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:
transitThe transit object
enabledenable 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.
