## 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

## ◆ elm_object_item_text_set

#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

  it | The Elementary object item.
  label | The 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

## ◆ Elm_Event_Policy_Changed

typedef struct _Elm_Event_Policy_Changed Elm_Event_Policy_Changed

Data on the event when an Elementary policy has changed.

## ◆ Elm_Event_Atspi_Bridge_State_Changed

typedef struct _Elm_Event_Atspi_Bridge_State_Changed Elm_Event_Atspi_Bridge_State_Changed

Data on event when atspi bridge state is changed.

Since
  1.26

## ◆ Elm_Event_Cb

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_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.

See also
  elm_object_item_signal_callback_add()

Since
  1.8

## ◆ Elm_Widget_Item

Elm_Widget_Item

An Elementary widget item handle.

This is a sub component of an Elementary widget and it is the same as Elementary object item, Elm_Object_Item. Common functions for Elementary widget item are provided on this page. Each Elementary widget also provides its own functions to use Elementary widget item. For more details about how Elementary widget item is used with Elementary widget, please refer each Elementary widget's documents.

## Enumeration Type Documentation

## ◆ Elm_Object_Select_Mode

enum Elm_Object_Select_Mode

Possible values for the selection policy of some widgets.

Since
  1.7

Enumerator
ELM_OBJECT_SELECT_MODE_DEFAULT | default select mode. Once an item is selected, it would stay highlighted and not going to call selected callback again even it was clicked. Items can get focus.
ELM_OBJECT_SELECT_MODE_ALWAYS | always select mode. Item selected callbacks will be called every time for click events, even after the item was already selected. Items can get focus.
ELM_OBJECT_SELECT_MODE_NONE | no select mode. Items will never be highlighted and selected but the size will be adjusted by the finger size configuration. Items can't get focus.
ELM_OBJECT_SELECT_MODE_DISPLAY_ONLY | no select mode with no finger size rule. Items will never be highlighted and selected and ignore the finger size. So the item size can be reduced below than the finger size configuration. Items can't get focus.
ELM_OBJECT_SELECT_MODE_MAX | canary value: any value greater or equal to ELM_OBJECT_SELECT_MODE_MAX is forbidden.

ELM_LIST_LIMIT | Sets a minimum size hint on the list object, so that containers may respect it (and resize itself to fit the child properly). More specifically, a minimum size hint will be set for its transverse axis, so that the largest item in that direction fits well. This is naturally bound by the list object's maximum size hints, set externally.
ELM_LIST_EXPAND | Besides setting a minimum size on the transverse axis, just like on ELM_LIST_LIMIT, the list will set a minimum size on the longitudinal axis, trying to reserve space to all its children to be visible at a time. .

## Function Documentation

## ◆ elm_object_domain_translatable_text_part_set()

EINA_DEPRECATED void elm_object_domain_translatable_text_part_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

  obj | The object containing the text part
  part | The name of the part to set
  domain | The translation domain to use
  text | The original, non-translated text to set

Deprecated:
  Use elm_object_domain_translatable_part_text_set() instead.

References elm_object_domain_translatable_part_text_set().

## ◆ elm_object_translatable_text_part_get()

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

  obj | The object
  part | The name of the part that was set

Returns
  The original, untranslated string

Deprecated:
  Use elm_object_translatable_part_text_get() instead.

References elm_object_translatable_part_text_get().

## ◆ elm_init()

int elm_init | ( | int | argc,
|  | char ** | argv
| ) |  |

Initialize Elementary.

Parameters

  [in] | argc | System's argument count value
  [in] | argv | System'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:

ELM_MAIN()
ELM_MAIN
#define ELM_MAIN()
macro to be used after the elm_main() function
Definition: elm_general.h:556

See the full example.

## ◆ elm_shutdown()

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()

Examples
  ephysics_logo.c.

Referenced by elm_quicklaunch_fork().

## ◆ elm_run()

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

Examples

References ecore_main_loop_begin().

## ◆ elm_exit()

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_example_00.c, efl_thread_3.c, efl_thread_4.c, efl_thread_5.c, fileselector_example.c, glview_example_01.c, progressbar_example.c, and win_example.c.

References efl_exit().

## ◆ elm_policy_set()

Eina_Bool elm_policy_set | ( | unsigned int | policy,
|  | int | value
| ) |  |

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

Parameters

  policy | policy identifier, as in Elm_Policy.
  value | policy 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.

Examples
  actionslider_example_01.c, bg_example_01.c, bg_example_02.c, bg_example_03.c, box_example_02.c, bubble_example_01.c, button_example_00.c, button_example_01.c, calendar_example_01.c, calendar_example_02.c, calendar_example_03.c, calendar_example_04.c, calendar_example_05.c, calendar_example_06.c, check_example_01.c, clock_example.c, codegen_example.c, colorselector_example_01.c, combobox_example_01.c, conformant_example_01.c, conformant_example_02.c, ctxpopup_example_01.c, datetime_example.c, dayselector_example.c, diskselector_example_01.c, diskselector_example_02.c, efl_thread_3.c, efl_thread_4.c, efl_thread_5.c, efl_thread_6.c, entry_example.c, ephysics_logo.c, fileselector_button_example.c, fileselector_entry_example.c, fileselector_example.c, flip_example_01.c, flipselector_example.c, frame_example_01.c, general_funcs_example.c, gengrid_example.c, genlist_example_01.c, genlist_example_02.c, genlist_example_03.c, genlist_example_04.c, genlist_example_05.c, glview_example_01.c, hover_example_01.c, hoversel_example_01.c, icon_example_01.c, image_example_01.c, index_example_01.c, index_example_02.c, inwin_example.c, label_example_01.c, layout_example_01.c, layout_example_02.c, layout_example_03.c, list_example_01.c, list_example_02.c, list_example_03.c, map_example_01.c, map_example_02.c, map_example_03.c, mapbuf_example.c, menu_example_01.c, naviframe_example.c, notify_example_01.c, panel_example_01.c, panes_example.c, photocam_example_01.c, popup_example_01.c, popup_example_02.c, popup_example_03.c, prefs_example_01.c, prefs_example_02.c, prefs_example_03.c, radio_example_01.c, scroller_example_01.c, segment_control_example.c, separator_example_01.c, slider_example.c, slideshow_example.c, spinner_example.c, table_example_01.c, table_example_02.c, theme_example_01.c, theme_example_02.c, thumb_example_01.c, toolbar_example_01.c, toolbar_example_02.c, toolbar_example_03.c, track_example_01.c, transit_example_01.c, transit_example_02.c, transit_example_03.c, transit_example_04.c, and web_example_02.c.

## ◆ elm_policy_get()

int elm_policy_get | ( | unsigned int | policy | ) |

Get the policy value for given policy identifier.

Parameters

  policy | policy identifier, as in Elm_Policy.

Returns
  The currently set policy value, for that identifier. Will be `0` if `policy` passed is invalid.

References ELM_POLICY_LAST.

## ◆ elm_language_set()

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

  lang | Language to set, must be the full name of the locale

References edje_language_set(), and evas_language_reinit().

## ◆ elm_process_state_get()

Elm_Process_State elm_process_state_get | ( | void |  | ) |

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.

|  | 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

  obj | The object containing the text part
  part | The part name of the translatable text
  domain | The translation domain to use
  translatable | `EINA_TRUE`, the part text will be translated internally. `EINA_FALSE`, otherwise.

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.

  obj | The object
  emission | The signal's name.
  source | The signal's source.

References EINA_SAFETY_ON_NULL_RETURN.

## ◆ elm_object_signal_callback_add()

Parameters

  obj | The object
  emission | The signal's name.
  source | The signal's source.
  func | The callback function to be executed when the signal is emitted.
  data | A pointer to data to pass to the callback function.

References EINA_SAFETY_ON_NULL_RETURN.

## ◆ elm_object_signal_callback_del()

Parameters

  obj | The object handle
  emission | The signal's name.
  source | The signal's source.
  func | The 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.

References EINA_SAFETY_ON_NULL_RETURN_VAL.

## ◆ elm_object_event_callback_add()

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

  obj | The widget to add an event callback on
  func | The callback function to be executed when the event happens
  data | Data 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.

## ◆ 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

  obj | The object
  func | The callback function to be executed when the event is emitted.
  data | Data to pass in to the callback function.

Returns
  The data pointer

void elm_object_orientation_mode_disabled_set | ( | Evas_Object * | obj,
|  | Eina_Bool | disabled
| ) |  |

## ◆ elm_object_item_signal_callback_del()

void * elm_object_item_signal_callback_del | ( | Elm_Widget_Item * | obj,
|  | const char * | emission,
|  | const char * | source,
|  | Elm_Object_Item_Signal_Cb | func
| ) |  |

Remove a signal-triggered callback from a object item edje object.

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

See: elm_object_item_signal_callback_add

Parameters

  [in] | obj | The object.
  [in] | emission | The signal's name.
  [in] | source | The signal's source.
  [in] | func | The callback function to be executed when the signal is emitted.

Returns
  The data pointer of the signal callback or `NULL`, on errors.

## ◆ elm_object_item_signal_emit()

void elm_object_item_signal_emit | ( | Elm_Widget_Item * | obj,
|  | const char * | emission,
|  | const char * | source
| ) |  |

Send a signal to the edje object of the widget item.

This function sends a signal to the edje object of the obj item. An edje program can respond to a signal by specifying matching 'signal' and 'source' fields. Don't use this unless you want to also handle resetting of part states to default on every unrealize in case of genlist/gengrid.

Parameters

  [in] | obj | The object.
  [in] | emission | The signal's name.
  [in] | source | The signal's source.

## ◆ elm_object_item_access_info_set()

void elm_object_item_access_info_set | ( | Elm_Widget_Item * | obj,
|  | const char * | txt
| ) |  |

Set the text to read out when in accessibility mode.

Parameters

  [in] | obj | The object.
  [in] | txt | The text that describes the widget to people with poor or no vision

## ◆ elm_object_item_access_object_get()

Efl_Canvas_Object * elm_object_item_access_object_get | ( | const Elm_Widget_Item * | obj | ) |

Get an accessible object of the object item.

Parameters

  [in] | obj | The object.

Returns
  Accessible object of the object item or NULL for any error

Since
  1.8

## ◆ elm_object_item_domain_translatable_part_text_set()

void elm_object_item_domain_translatable_part_text_set | ( | Elm_Widget_Item * | obj,
|  | const char * | part,
|  | const char * | domain,
|  | const char * | label
| ) |  |

Set the text for an object item'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 item using elm_object_item_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

  [in] | obj | The object.
  [in] | part | The name of the part to set
  [in] | domain | The translation domain to use
  [in] | label | The original, non-translated text to set

Since
  1.8

## ◆ elm_object_item_translatable_part_text_get()

const char * elm_object_item_translatable_part_text_get | ( | const Elm_Widget_Item * | obj,
|  | const char * | part
| ) |  |

Get the original string set as translatable for an object item.

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

Parameters

  [in] | obj | The object.
  [in] | part | The name of the part that was set

Returns
  The original, untranslated string

Since
  1.8

## ◆ elm_object_item_domain_part_text_translatable_set()

void elm_object_item_domain_part_text_translatable_set | ( | Elm_Widget_Item * | 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_item_part_text_set and elm_object_item_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.

See: elm_object_item_domain_translatable_part_text_set See: elm_object_item_part_text_set See: elm_policy()

Parameters

  [in] | obj | The object.
  [in] | part | The part name of the translatable text
  [in] | domain | The translation domain to use
  [in] | translatable | `true`, the part text will be translated internally. `false`, otherwise.

## ◆ elm_object_item_track()

Efl_Canvas_Object * elm_object_item_track | ( | Elm_Widget_Item * | obj | ) |

This returns track object of the item.

Note
  This gets a rectangle object that represents the object item's internal object. If you want to check the geometry, visibility of the item, you can call the evas apis such as evas_object_geometry_get(), evas_object_visible_get() to the track object. Note that all of the widget items may/may not have the internal object so this api may return `NULL` if the widget item doesn't have it. Additionally, the widget item is managed/controlled by the widget, the widget item could be changed(moved, resized even deleted) anytime by it's own widget's decision. So please don't change the track object as well as don't keep the track object in your side as possible but get the track object at the moment you need to refer. Otherwise, you need to add some callbacks to the track object to track it's attributes changes.

Warning
  After use the track object, please call the elm_object_item_untrack() paired to elm_object_item_track definitely to free the track object properly. Don't delete the track object.

See: elm_object_item_untrack See: elm_object_item_track_get

Parameters

  [in] | obj | The object.

Returns
  The track object

Since
  1.8

## ◆ elm_object_item_untrack()

void elm_object_item_untrack | ( | Elm_Widget_Item * | obj | ) |

This retrieve the track object of the item.

Note
  This retrieves the track object that was returned from elm_object_item_track.

See: elm_object_item_track See: elm_object_item_track_get

Parameters

  [in] | obj | The object.

Since
  1.8

## ◆ elm_object_item_track_get()

int elm_object_item_track_get | ( | const Elm_Widget_Item * | obj | ) |

Get the track object reference count.

Note
  This gets the reference count for the track object. Whenever you call the elm_object_item_track, the reference count will be increased by one. Likely the reference count will be decreased again when you call the elm_object_item_untrack. Unless the reference count reaches to zero, the track object won't be deleted. So please be sure to call elm_object_item_untrack() paired to the elm_object_item_track call count.

See: elm_object_item_track See: elm_object_item_track_get

Parameters

  [in] | obj | The object.

Returns
  Track object reference count

|  | const void * | data,
|  | Evas_Smart_Cb | del_cb
| ) |  |

Set the content to be shown in the tooltip item.

Setup the tooltip to item. The item can have only one tooltip, so any previous tooltip data is removed. `func`(with `data`) will be called every time that need show the tooltip and it should return a valid Evas_Object. This object is then managed fully by tooltip system and is deleted when the tooltip is gone.

See: elm_object_tooltip_content_cb_set() for more details.

Parameters

  [in] | obj | The object.
  [in] | func | The function used to create the tooltip contents.
  [in] | data | What to provide to `func` as callback data/context.
  [in] | del_cb | Called when data is not needed anymore, either when another callback replaces `func`, the tooltip is unset with elm_object_item_tooltip_unset or the owner `item` dies. This callback receives as the first parameter the given `data`, and `event_info` is the item.
