Tizen Native API  5.5

icon_inheritance_tree.png

An icon object is used to display standard icon images ("delete", "edit", "arrows", etc.) or images coming from a custom file (PNG, JPG, EDJE, etc.), on icon contexts.

The icon image requested can be in the Elementary theme in use, or in the freedesktop.org theme paths. It's possible to set the order of preference from where an image will be fetched.

This widget inherits from the mapping one, so that all the functions acting on it also work for icon objects.

You should be using an icon, instead of an image, whenever one of the following apply:

  • you need a thumbnail version of an original image
  • you need freedesktop.org provided icon images
  • you need theme provided icon images (Edje groups)

Various calls on the icon's API are marked as deprecated, as they just wrap the image counterpart functions. Use the ones we point you to, for each case of deprecation here, instead -- eventually the deprecated ones will be discarded (next major release).

Default images provided by Elementary's default theme are described below.

These are names that follow (more or less) the Freedesktop icon naming specification. Use of these names are preferred, at least if you want to give your user the ability to use other themes. All these icons can be seen in the elementary_test application, the test is called "Icon Standard".

  • "folder" (since 1.13)
  • "user-home" (since 1.13)
  • "user-trash" (since 1.13)
  • "view-close" (since 1.13)
  • "view-refresh" (since 1.13)
  • "window-close" (since 1.13)
  • "document-close" (since 1.13)
  • "document-edit" (since 1.13)
  • "dialog-info" (since 1.13)

  • "media-eject" (since 1.13)
  • "audio-volume" (since 1.13)
  • "audio-volume-muted" (since 1.13)

There is also a selection of old names that were used before standard names were being encouraged. These should be considered deprecated and one of the names above used instead.

  • "arrow_up" (since 1.13)
  • "arrow_down" (since 1.13)
  • "arrow_left" (since 1.13)
  • "arrow_right" (since 1.13)
  • "search" (since 1.13)

These are names for icons that were first intended to be used in toolbars, but can be used in many other places too:

  • "home"
  • "close"
  • "apps"
  • "arrow_up"
  • "arrow_down"
  • "arrow_left"
  • "arrow_right"
  • "chat"
  • "clock"
  • "delete"
  • "edit"
  • "refresh"
  • "folder"
  • "file"

These are names for icons that were designed to be used in menus (but again, you can use them anywhere else):

  • "menu/home"
  • "menu/close"
  • "menu/apps"
  • "menu/arrow_up"
  • "menu/arrow_down"
  • "menu/arrow_left"
  • "menu/arrow_right"
  • "menu/chat"
  • "menu/clock"
  • "menu/delete"
  • "menu/edit"
  • "menu/refresh"
  • "menu/folder"
  • "menu/file"

And these are names for some media player specific icons:

  • "media_player/forward"
  • "media_player/info"
  • "media_player/next"
  • "media_player/pause"
  • "media_player/play"
  • "media_player/prev"
  • "media_player/rewind"
  • "media_player/stop"

This widget emits the following signals, besides the ones sent from Image:

Elementary icon objects support the following API calls:

An example of usage for this API follows:

Functions

Evas_Objectelm_icon_add (Evas_Object *parent)
void elm_icon_thumb_set (Evas_Object *obj, const char *file, const char *group)
 Set the file that will be used, but use a generated thumbnail.
void elm_icon_order_lookup_set (Evas_Object *obj, Elm_Icon_Lookup_Order order)
 Sets the icon lookup order used by elm_icon_standard_set().
Elm_Icon_Lookup_Order elm_icon_order_lookup_get (const Evas_Object *obj)
 Get the icon lookup order.
Eina_Bool elm_icon_standard_set (Evas_Object *obj, const char *name)
 Set the icon by icon standards names.
const char * elm_icon_standard_get (const Evas_Object *obj)
 Get the icon name set by icon standard names.

Enumeration Type Documentation

Lookup order used by elm_icon_standard_set(). Should look for icons in the theme, FDO paths, or both?

Deprecated:
Prefer using elm_config "icon_theme" instead.
Enumerator:
ELM_ICON_LOOKUP_THEME_FDO 

Icon look up order: freedesktop, theme.

ELM_ICON_LOOKUP_FDO 

Icon look up order: theme, freedesktop.

ELM_ICON_LOOKUP_THEME

Elementary icon types

Enumerator:
ELM_ICON_NONE 

Icon has no type set

ELM_ICON_FILE

ELM_ICON_STANDARD 

Icon is of type standard


Function Documentation

Get the icon lookup order.

See also elm_icon_order_lookup_set, Elm_Icon_Lookup_Order.

Returns:
The icon lookup order (can be one of ELM_ICON_LOOKUP_FDO_THEME, ELM_ICON_LOOKUP_THEME_FDO, ELM_ICON_LOOKUP_FDO or ELM_ICON_LOOKUP_THEME)
Since :
2.3.1
Since :
2.3.1

Sets the icon lookup order used by elm_icon_standard_set().

See also elm_icon_order_lookup_get, Elm_Icon_Lookup_Order.

Parameters:
[in]orderThe icon lookup order (can be one of ELM_ICON_LOOKUP_FDO_THEME, ELM_ICON_LOOKUP_THEME_FDO, ELM_ICON_LOOKUP_FDO or ELM_ICON_LOOKUP_THEME)
Since :
2.3.1
Since :
2.3.1
const char* elm_icon_standard_get ( const Evas_Object obj)

Get the icon name set by icon standard names.

If the icon image was set using elm_image_file_set() instead of elm_icon_standard_set, then this function will return null.

Returns:
The icon name
Since :
2.3.1
Examples:
icon_example_01.c.
Eina_Bool elm_icon_standard_set ( Evas_Object obj,
const char *  name 
)

Set the icon by icon standards names.

For example, freedesktop.org defines standard icon names such as "go-home", "network-wired", etc. There can be different icon sets to match those icon keys. The "name" given as parameter is one of these "keys", and will be used to look in the freedesktop.org paths and elementary theme.

If name is not found in any of the expected locations and it is the absolute path of an image file, this image will be used.

Note:
The icon image set by this function can be changed by Efl::File::file::set.
This function does not accept relative icon path.

See also elm_icon_standard_get.

Parameters:
[in]nameThe icon name
Returns:
true on success, false on error
Since :
2.3.1
Examples:
button_example_01.c, ctxpopup_example_01.c, diskselector_example_02.c, fileselector_button_example.c, fileselector_entry_example.c, genlist_example_01.c, genlist_example_02.c, genlist_example_03.c, genlist_example_04.c, genlist_example_05.c, icon_example_01.c, layout_example_01.c, layout_example_02.c, list_example_03.c, mapbuf_example.c, radio_example_01.c, segment_control_example.c, slider_example.c, and web_example_02.c.
void elm_icon_thumb_set ( Evas_Object obj,
const char *  file,
const char *  group 
)

Set the file that will be used, but use a generated thumbnail.

This functions like elm_image_file_set() but requires the Ethumb library support to be enabled successfully with elm_need_ethumb. When set the file indicated has a thumbnail generated and cached on disk for future use or will directly use an existing cached thumbnail if it is valid.

Parameters:
[in]fileThe path to file that will be used as icon image
[in]groupThe group that the icon belongs to an edje file
Since :
2.3.1
