Detailed Description

General Elementary API.

Functions that don't relate to Elementary objects specifically.

Here are documented functions which init/shutdown the library, that apply to generic Elementary objects, that deal with configuration, et cetera.

This example contemplates some of these functions.

Macro Definition Documentation

#define elm_object_item_text_set (   it,
  label 
)    elm_object_item_part_text_set((it), NULL, (label))

Macro to set a label of an object item.

Parameters
itThe Elementary object item.
labelThe new text of the label.
Note
Elementary object items may have many labels.
Examples:
popup_example_03.c, segment_control_example.c, and web_example_02.c.

Typedef Documentation

typedef Eina_Bool(* Elm_Event_Cb) (void *data, Evas_Object *obj, Evas_Object *src, Evas_Callback_Type type, void *event_info)

Function prototype definition for callbacks on input events happening on Elementary widgets.

data will receive the user data pointer passed to elm_object_event_callback_add(). src will be a pointer to the widget on which the input event took place. type will get the type of this event and event_info, the struct with details on this event.

Elm_Object_Item_Signal_Cb

Elm_Object_Item Signal Callback functions' prototype definition.

data will have the auxiliary data pointer at the time the callback registration. it will be a pointer the Elm_Object_Item that have the edje object where the signal comes from. emission will identify the exact signal's emission string and source the exact signal's source one.

elm_object_item_signal_callback_add()
Since
1.8

Enumeration Type Documentation

Defines couple of standard Evas_Object layers to be used with evas_object_layer_set().

Note
whenever extending with new values, try to keep some padding to siblings so there is room for further extensions.
Enumerator
ELM_OBJECT_LAYER_BACKGROUND 

where to place backgrounds

ELM_OBJECT_LAYER_DEFAULT 

Evas_Object default layer (and thus for Elementary)

ELM_OBJECT_LAYER_FOCUS 

where focus object visualization is

ELM_OBJECT_LAYER_TOOLTIP 

where to show tooltips

ELM_OBJECT_LAYER_CURSOR 

where to show cursors

ELM_OBJECT_LAYER_LAST 

last layer known by Elementary

Function Documentation

void elm_exit ( void  )

Ask to exit Elementary's main loop.

If this call is issued, it will flag the main loop to cease processing and return back to its parent function (usually your elm_main() function). This does not mean the main loop instantly quits. So your ecore callbacks(timer, animator, event, job, and etc.) have chances to be called even after elm_exit().

See also
elm_init() for an example. There, just after a request to close the window comes, the main loop will be left.
Note
By using the appropriate #ELM_POLICY_QUIT on your Elementary applications, you'll be able to get this function called automatically for you.
Examples:
button_cxx_example_00.cc, button_example_00.c, efl_thread_4.c, efl_thread_5.c, fileselector_example.c, glview_cxx_example_01.cc, glview_example_01.c, progressbar_example.c, and win_example.c.

References elm_policy_get().

int elm_init ( int  argc,
char **  argv 
)

Initialize Elementary.

Parameters
[in]argcSystem's argument count value
[in]argvSystem's pointer to array of argument strings
Returns
The init counter value.

This function initializes Elementary and increments a counter of the number of calls to it. It returns the new counter's value.

Warning
This call is exported only for use by the ELM_MAIN() macro. There is no need to use this if you use this macro (which is highly advisable). An elm_main() should contain the entry point code for your application, having the same prototype as elm_init(), and not being static (putting the EAPI_MAIN symbol in front of its type declaration is advisable). The ELM_MAIN() call should be placed just after it.

Example:

1 ELM_MAIN()

See the full example.

elm_shutdown().

References elm_quicklaunch_init(), and elm_quicklaunch_sub_init().

void elm_language_set ( const char *  lang)

Change the language of the current application.

The lang passed must be the full name of the locale to use, for example "en_US.utf8" or "es_ES@euro".

Changing language with this function will make Elementary run through all its widgets, translating strings set with elm_object_domain_translatable_part_text_set(). This way, an entire UI can have its language changed without having to restart the program.

For more complex cases, like having formatted strings that need translation, widgets will also emit a "language,changed" signal that the user can listen to and manually translate the text.

Parameters
langLanguage to set, must be the full name of the locale
const char* elm_object_access_info_get ( Evas_Object *  obj)

Get the text to read out when in accessibility mode.

Parameters
objThe object which is to be described
Returns
The text that describes the widget to people with poor or no vision
Since
1.14
void elm_object_access_info_set ( Evas_Object *  obj,
const char *  txt 
)

Set the text to read out when in accessibility mode.

Parameters
objThe object which is to be described
txtThe text that describes the widget to people with poor or no vision
Eina_Bool elm_object_disabled_get ( const Evas_Object *  obj)

Get the disabled state of an Elementary object.

Parameters
objThe Elementary object to operate on
Returns
EINA_TRUE, if the widget is disabled, EINA_FALSE if it's enabled (or on errors)

This gets the state of the widget, which might be enabled or disabled.

void elm_object_disabled_set ( Evas_Object *  obj,
Eina_Bool  disabled 
)

Set the disabled state of an Elementary object.

Parameters
objThe Elementary object to operate on
disabledThe state to put in in: EINA_TRUE for disabled, EINA_FALSE for enabled

Elementary objects can be disabled, in which state they won't receive input and, in general, will be themed differently from their normal state, usually greyed out. Useful for contexts where you don't want your users to interact with some of the parts of you interface.

This sets the state for the widget, either disabling it or enabling it back.

void elm_object_domain_part_text_translatable_set ( Evas_Object *  obj,
const char *  part,
const char *  domain,
Eina_Bool  translatable 
)

Mark the part text to be translatable or not.

Once you mark the part text to be translatable, the text will be translated internally regardless of elm_object_part_text_set() and elm_object_domain_translatable_part_text_set(). In other case, if you set the Elementary policy that all text will be translatable in default, you can set the part text to not be translated by calling this API.

Parameters
objThe object containing the text part
partThe part name of the translatable text
domainThe translation domain to use
translatableEINA_TRUE, the part text will be translated internally. EINA_FALSE, otherwise.

Since
1.8
void elm_object_domain_translatable_part_text_set ( Evas_Object *  obj,
const char *  part,
const char *  domain,
const char *  text 
)

Set the text for an object's part, marking it as translatable.

The string to set as text must be the original one. Do not pass the return of gettext() here. Elementary will translate the string internally and set it on the object using elm_object_part_text_set(), also storing the original string so that it can be automatically translated when the language is changed with elm_language_set().

The domain will be stored along to find the translation in the correct catalog. It can be NULL, in which case it will use whatever domain was set by the application with textdomain(). This is useful in case you are building a library on top of Elementary that will have its own translatable strings, that should not be mixed with those of programs using the library.

Parameters
objThe object containing the text part
partThe name of the part to set
domainThe translation domain to use
textThe original, non-translated text to set
Since
1.8

EINA_DEPRECATED void elm_object_domain_translatable_text_part_set ( Evas_Object *  obj,
const char *  part,
const char *  domain,
const char *  text 
)

The string to set as text must be the original one. Do not pass the return of gettext() here. Elementary will translate the string internally and set it on the object using elm_object_part_text_set(), also storing the original string so that it can be automatically translated when the language is changed with elm_language_set().

textThe original, non-translated text to set
Deprecated:
Use elm_object_domain_translatable_part_text_set() instead.

void elm_object_event_callback_add ( Evas_Object *  obj,
Elm_Event_Cb  func,
const void *  data 
)

Add a callback for input events (key up, key down, mouse wheel) on a given Elementary widget.

Parameters
objThe widget to add an event callback on
funcThe callback function to be executed when the event happens
dataData to pass in to func

Every widget in an Elementary interface set to receive focus, with elm_object_focus_allow_set(), will propagate all of its key up, key down and mouse wheel input events up to its parent object, and so on. All of the focusable ones in this chain which had an event callback set, with this call, will be able to treat those events. There are two ways of making the propagation of these event upwards in the tree of widgets to cease:

  • Just return EINA_TRUE on func. EINA_FALSE will mean the event was not processed, so the propagation will go on.
  • The event_info pointer passed to func will contain the event's structure and, if you OR its event_flags inner value to EVAS_EVENT_FLAG_ON_HOLD, you're telling Elementary one has already handled it, thus killing the event's propagation, too.
Note
Your event callback will be issued on those events taking place only if no other child widget of obj has consumed the event already.
Not to be confused with evas_object_event_callback_add(), which will add event callbacks per type on general Evas objects (no event propagation infrastructure taken in account).
Not to be confused with elm_object_signal_callback_add(), which will add callbacks to signals coming from a widget's theme, not input events.
Not to be confused with edje_object_signal_callback_add(), which does the same as elm_object_signal_callback_add(), but directly on an Edje object.
Not to be confused with evas_object_smart_callback_add(), which adds callbacks to smart objects' smart events, and not input events.
See also
elm_object_event_callback_del()
void* elm_object_event_callback_del ( Evas_Object *  obj,
Elm_Event_Cb  func,
const void *  data 
)

Remove an event callback from a widget.

This function removes a callback, previously attached to event emission by the obj. The parameters func and data must match exactly those passed to a previous call to elm_object_event_callback_add(). The data pointer that was passed to this call will be returned.

Parameters
objThe object
funcThe callback function to be executed when the event is emitted.
dataData to pass in to the callback function.
Returns
The data pointer
void* elm_object_item_data_get ( const Elm_Object_Item it)

Get the data associated with an object item.

Parameters
itThe Elementary object item
Returns
The data associated with it
Note
Every elm_object_item supports this API
Examples:
entry_example.c, gengrid_example.c, genlist_example_05.c, index_example_01.c, index_example_02.c, and slideshow_example.c.
void elm_object_item_data_set ( Elm_Object_Item it,
void *  data 
)

Set the data associated with an object item.

Parameters
itThe Elementary object item
dataThe data to be associated with it
Note
Every elm_object_item supports this API
Evas_Object* elm_object_name_find ( const Evas_Object *  obj,
const char *  name,
int  recurse 
)

Get a named object from the children.

Parameters
objThe parent object whose children to look at
nameThe name of the child to find
recurseSet to the maximum number of levels to recurse (0 == none, 1 is only look at 1 level of children etc.)
Returns
The found object of that name, or NULL if none is found

This function searches the children (or recursively children of children and so on) of the given obj object looking for a child with the name of name. If the child is found the object is returned, or NULL is returned. You can set the name of an object with evas_object_name_set(). If the name is not unique within the child objects (or the tree is recurse is greater than 0) then it is undefined as to which child of that name is returned, so ensure the name is unique amongst children. If recurse is set to -1 it will recurse without limit.

Eina_Bool elm_object_orientation_mode_disabled_get ( const Evas_Object *  obj)

Get the orientation mode of a given widget.

Parameters
objThe Elementary widget to query for its orientation mode.
Returns
EINA_TRUE, if the orientation mode is disabled, EINA_FALSE if the orientation mode is enabled (or on errors)
See also
elm_object_orientation_mode_disabled_set()
Since
1.8
void elm_object_orientation_mode_disabled_set ( Evas_Object *  obj,
Eina_Bool  disabled 
)

Disable the orientation mode of a given widget.

Orientation Mode is used for widgets to change it's styles or to send signals whenever it's window degree is changed. If the orientation mode is enabled and the widget has different looks and styles for the window degree(0, 90, 180, 270), it will apply a style that is readied for the current degree, otherwise, it will send signals to it's own edje to change it's states if the style doesn't be readied.

Parameters
objThe Elementary object to operate on orientation mode.
disabledThe state to put in in: EINA_TRUE for disabled, EINA_FALSE for enabled.

)

Get the content on a part of a given container widget.

Parameters
objThe Elementary container widget
partThe container's part name to get (some might accept NULL for the default part)

sourceThe signal's source.
funcThe callback function to be executed when the signal is emitted.
Returns
The data pointer of the signal callback or NULL, on errors.

This function removes the last callback, previously attached to a signal emitted by an underlying Edje object of obj, whose parameters emission, source and func match exactly with those passed to a previous call to elm_object_signal_callback_add(). The data pointer that was passed to this call will be returned.

void elm_object_signal_emit ( Evas_Object *  obj,
const char *  emission,
const char *  source 
)

Parameters
objThe object
partThe name of the part that was set
Returns
The original, untranslated string

EINA_DEPRECATED const char* elm_object_translatable_text_part_get ( const Evas_Object *  obj,
const char *  part 
)

Get the original string set as translatable for an object.

When setting translated strings, the function elm_object_part_text_get() will return the translation returned by gettext(). To get the original string use this function.

Parameters
objThe object
partThe name of the part that was set
Returns
The original, untranslated string

int elm_policy_get ( unsigned int  policy)

Get the policy value for given policy identifier.

Parameters
policypolicy identifier, as in #Elm_Policy.
Returns
The currently set policy value, for that identifier. Will be 0 if policy passed is invalid.

Referenced by elm_exit().

Eina_Bool elm_policy_set ( unsigned int  policy,
int  value 
)

Set a new policy's value (for a given policy group/identifier).

Parameters
policypolicy identifier, as in Elm_Policy.
valuepolicy value, which depends on the identifier
Returns
EINA_TRUE on success or EINA_FALSE, on error.

Elementary policies define applications' behavior, somehow. These behaviors are divided in policy groups (see #Elm_Policy enumeration). This call will emit the Ecore event ELM_EVENT_POLICY_CHANGED, which can be hooked at with handlers. An #Elm_Event_Policy_Changed struct will be passed, then.

Note
Currently, we have only one policy identifier/group (#ELM_POLICY_QUIT), which has two possible values.

Elm_Process_State elm_process_state_get ( void  )

The state of the process as a whole.

Since
1.12 Get the process state as a while
Returns
The current process state

The process may logically be some runnable state. a "foreground" application runs as normal and may be user-visible or "active" in some way. A background application is not user-visible or otherwise important and likely should release resources and not wake up often or process much.

Since
1.12
void elm_run ( void  )

Run Elementary's main loop.

This call should be issued just after all initialization is completed. This function will not return until elm_exit() is called. It will keep looping, running the main (event/processing) loop for Elementary.

This function should be called once only from the same thread that initted elementary, (elm_init(), eina_init(), ...) and should never be nested. Never call it from within an instance of itself.

See also
elm_init() for an example

int elm_shutdown ( void  )

Shut down Elementary.

Returns
The init counter value.

This should be called at the end of your application, just before it ceases to do any more processing. This will clean up any permanent resources your application may have allocated via Elementary that would otherwise persist.

See also
elm_init() for an example
Note
elm_shutdown() will iterate main loop until all ecore_evas are freed. There is a possibility to call your ecore callbacks(timer, animator, event, job, and etc.) in elm_shutdown()
