Detailed Description


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 Image 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 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:
"thumb,done"
- elm_icon_thumb_set() has completed with success (- Since:
- 1.7)
"thumb,error"
- elm_icon_thumb_set() has failed (- Since:
- 1.7)
- elm_object_signal_emit()
- elm_object_signal_callback_add()
- elm_object_signal_callback_del() for emmiting and listening to signals on the object, when the internal image comes from an Edje object. This behavior was added unintentionally, though, and is deprecated. Expect it to be dropped on future releases.

Function Documentation
Evas_Object* elm_icon_add | ( | Evas_Object * | parent | ) |
Add a new icon object to the parent.
- Parameters:
-
parent The parent object
- Returns:
- The new object or NULL if it cannot be created
- See also:
- elm_image_file_set()
Referenced by elm_menu_item_add(), elm_toolbar_item_icon_file_set(), elm_toolbar_item_icon_memfile_set(), elm_toolbar_item_icon_set(), and elm_toolbar_item_state_add().
EINA_DEPRECATED Eina_Bool elm_icon_animated_available_get | ( | const Evas_Object * | obj | ) |
Get if the icon supports animation or not.
- Parameters:
-
obj The icon object
- Returns:
EINA_TRUE
if the icon supports animation,EINA_FALSE
otherwise.
Return if this elm icon's image can be animated. Currently Evas only supports gif animation. If the return value is EINA_FALSE, other elm_icon_animated_xxx APIs won't work.
- Deprecated:
- Use elm_image_animated_available_get() instead.
References elm_image_animated_available_get().
EINA_DEPRECATED Eina_Bool elm_icon_animated_get | ( | const Evas_Object * | obj | ) |
Get animation mode of the icon.
- Parameters:
-
obj The icon object
- Returns:
- The animation mode of the icon object
- See also:
- elm_icon_animated_set
- Deprecated:
- Use elm_image_animated_get() instead.
References elm_image_animated_get().
EINA_DEPRECATED Eina_Bool elm_icon_animated_play_get | ( | const Evas_Object * | obj | ) |
Get animation play mode of the icon.
- Parameters:
-
obj The icon object
- Returns:
- The play mode of the icon object
- See also:
- elm_icon_animated_play_get
- Deprecated:
- Use elm_image_animated_play_get() instead.
References elm_image_animated_play_get().
EINA_DEPRECATED void elm_icon_animated_play_set | ( | Evas_Object * | obj, |
Eina_Bool | play | ||
) |
Set animation play mode of the icon.
- Parameters:
-
obj The icon object play EINA_TRUE
the object play animation images,EINA_FALSE
otherwise. Default isEINA_FALSE
.
To play elm icon's animation, set play to EINA_TRUE. For example, you make gif player using this set/get API and click event. This literally lets you control current play or paused state. To have this work with animated GIF files for example, you first, before setting the file have to use elm_icon_animated_set() to enable animation at all on the icon.
1. Click event occurs 2. Check play flag using elm_icon_animated_play_get 3. If elm icon was playing, set play to EINA_FALSE. Then animation will be stopped and vice versa
- Deprecated:
- Use elm_image_animated_play_set() instead.
References elm_image_animated_play_set().
EINA_DEPRECATED void elm_icon_animated_set | ( | Evas_Object * | obj, |
Eina_Bool | animated | ||
) |
Set animation mode of the icon.
- Parameters:
-
obj The icon object animated EINA_TRUE
if the object do animation job,EINA_FALSE
otherwise. Default isEINA_FALSE
.
Since the default animation mode is set to EINA_FALSE, the icon is shown without animation. Files like animated GIF files can animate, and this is supported if you enable animated support on the icon. Set it to EINA_TRUE when the icon needs to be animated.
- Deprecated:
- Use elm_image_animated_set() instead.
References elm_image_animated_set().
EINA_DEPRECATED Eina_Bool elm_icon_aspect_fixed_get | ( | const Evas_Object * | obj | ) |
Get if the object retains the original aspect ratio.
- Parameters:
-
obj The icon object.
- Returns:
EINA_TRUE
if the object keeps the original aspect,EINA_FALSE
otherwise.
- Deprecated:
- Use elm_image_aspect_fixed_get() instead.
References elm_image_aspect_fixed_get().
EINA_DEPRECATED void elm_icon_aspect_fixed_set | ( | Evas_Object * | obj, |
Eina_Bool | fixed | ||
) |
Set whether the original aspect ratio of the icon should be kept on resize.
- Parameters:
-
obj The icon object. fixed EINA_TRUE
if the icon should retain the aspect,EINA_FALSE
otherwise.
The original aspect ratio (width / height) of the icon is usually distorted to match the object's size. Enabling this option will retain this original aspect, and the way that the icon is fit into the object's area depends on the option set by elm_icon_fill_outside_set().
- Deprecated:
- Use elm_image_aspect_fixed_set() instead.
References elm_image_aspect_fixed_set().
EINA_DEPRECATED void elm_icon_file_get | ( | const Evas_Object * | obj, |
const char ** | file, | ||
const char ** | group | ||
) |
Get the file that will be used as icon.
- Parameters:
-
obj The icon object file The path to file that will be used as the icon image group The group that the icon belongs to, in edje file
- See also:
- elm_image_file_set()
- Deprecated:
- Use elm_image_file_get() instead.
References elm_image_file_get().
EINA_DEPRECATED Eina_Bool elm_icon_file_set | ( | Evas_Object * | obj, |
const char * | file, | ||
const char * | group | ||
) |
Set the file that will be used as icon.
- Parameters:
-
obj The icon object file The path to file that will be used as icon image group The group that the icon belongs to an edje file
- Returns:
- (
EINA_TRUE
= success,EINA_FALSE
= error)
- Note:
- The icon image set by this function can be changed by elm_icon_standard_set().
- See also:
- elm_icon_file_get()
- Deprecated:
- Use elm_image_file_set() instead.
References elm_image_file_set().
EINA_DEPRECATED Eina_Bool elm_icon_fill_outside_get | ( | const Evas_Object * | obj | ) |
Get if the object is filled outside.
- Parameters:
-
obj The icon object
- Returns:
EINA_TRUE
if the object is filled outside,EINA_FALSE
otherwise.
- See also:
- elm_icon_fill_outside_set()
- Deprecated:
- Use elm_image_fill_outside_get() instead.
References elm_image_fill_outside_get().
EINA_DEPRECATED void elm_icon_fill_outside_set | ( | Evas_Object * | obj, |
Eina_Bool | fill_outside | ||
) |
Set if the icon fill the entire object area.
- Parameters:
-
obj The icon object fill_outside EINA_TRUE
if the object is filled outside,EINA_FALSE
otherwise. Default isEINA_FALSE
.
When the icon object is resized to a different aspect ratio from the original icon image, the icon image will still keep its aspect. This flag tells how the image should fill the object's area. They are: keep the entire icon inside the limits of height and width of the object (fill_outside
is EINA_FALSE
) or let the extra width or height go outside of the object, and the icon will fill the entire object (fill_outside
is EINA_TRUE
).
- Note:
- Unlike Image, there's no option in icon to set the aspect ratio retain property to false. Thus, the icon image will always keep its original aspect ratio.
- See also:
- elm_icon_fill_outside_get()
- Deprecated:
- Use elm_image_fill_outside_set() instead.
References elm_image_fill_outside_set().
EINA_DEPRECATED Eina_Bool elm_icon_memfile_set | ( | Evas_Object * | obj, |
const void * | img, | ||
size_t | size, | ||
const char * | format, | ||
const char * | key | ||
) |
Set a location in memory to be used as an icon.
- Parameters:
-
obj The icon object img The binary data that will be used as an image size The size of binary data img
format Optional format of img
to pass to the image loaderkey Optional key of img
to pass to the image loader (eg. ifimg
is an edje file)
The format
string should be something like "png", "jpg", "tga", "tiff", "bmp" etc. if it is provided (NULL if not). This improves the loader performance as it tries the "correct" loader first before trying a range of other possible loaders until one succeeds.
- Returns:
- (
EINA_TRUE
= success,EINA_FALSE
= error)
- Note:
- The icon image set by this function can be changed by elm_icon_standard_set().
- Deprecated:
- Use elm_image_memfile_set() instead.
References elm_image_memfile_set().

- Parameters:
-
obj The icon object. no_scale EINA_TRUE
if the object is not scalable,EINA_FALSE
otherwise. Default isEINA_FALSE
.
This function disables scaling of the icon object through the function elm_object_scale_set(). However, this does not affect the object size/resize in any way. For that effect, take a look at elm_icon_resizable_set().
- Deprecated:

int | size | ||
) |
Set the prescale size for the icon.
- Parameters:
-
obj The icon object size The prescale size. This value is used for both width and height.
This function sets a new size for pixmap representation of the given icon. It allows the icon to be loaded already in the specified size, reducing the memory usage and load time when loading a big icon with load size set to a smaller size.
It's equivalent to the elm_bg_load_size_set() function for bg.
- Note:
- this is just a hint, the real size of the pixmap may differ depending on the type of icon being loaded, being bigger than requested.
- Deprecated:
- Use elm_image_prescale_set() instead.

Get if the object is (up/down) resizable.
- Parameters:
-
obj The icon object size_up A bool to set if the object is resizable up size_down A bool to set if the object is resizable down
- See also:

- Parameters:
-
obj The icon object size_up A bool to set if the object is resizable up. Default is EINA_TRUE
.size_down A bool to set if the object is resizable down. Default is EINA_TRUE

- elm_icon_resizable_get()
- Deprecated:
- Use elm_image_resizable_set() instead.
References elm_image_resizable_set().
EINA_DEPRECATED void elm_icon_size_get | ( | const Evas_Object * | obj, |
int * | w, | ||
int * | h | ||
) |
Get the object's image size.
- Parameters:
-
obj The icon object w A pointer to store the width in h A pointer to store the height in
- Deprecated:
- Use elm_image_object_size_get() instead.
References elm_image_object_size_get().
EINA_DEPRECATED Eina_Bool elm_icon_smooth_get | ( | const Evas_Object * | obj | ) |
Get whether smooth scaling is enabled for an icon object.
- Parameters:
-
obj The icon object
- Returns:
EINA_TRUE
if smooth scaling is enabled,EINA_FALSE
otherwise.
- See also:
- elm_icon_smooth_set()
- Deprecated:
- Use elm_image_smooth_get() instead.
References elm_image_smooth_get().
EINA_DEPRECATED void elm_icon_smooth_set | ( | Evas_Object * | obj, |
Eina_Bool | smooth | ||
) |
Set the smooth scaling for an icon object.
- Parameters:
-
obj The icon object smooth EINA_TRUE
if smooth scaling should be used,EINA_FALSE
otherwise. Default isEINA_TRUE
.
Set the scaling algorithm to be used when scaling the icon image. Smooth scaling provides a better resulting image, but is slower.
The smooth scaling should be disabled when making animations that change the icon size, since they will be faster. Animations that don't require resizing of the icon can keep the smooth scaling enabled (even if the icon is already scaled, since the scaled icon image will be cached).

- elm_icon_smooth_get()
- Deprecated:
- Use elm_image_smooth_set() instead.
References elm_image_smooth_set().
const char* elm_icon_standard_get | ( | const Evas_Object * | obj | ) |
Get the icon name set by icon standard names.
- Parameters:
-
obj The icon object
- Returns:
- The icon name
If the icon image was set using elm_image_file_set() instead of elm_icon_standard_set(), then this function will return NULL
.
- See also:
- elm_icon_standard_set()
Eina_Bool elm_icon_standard_set | ( | Evas_Object * | obj, |
const char * | name | ||
) |
Set the icon by icon standards names.
- Parameters:
-
obj The icon object name The icon name
- Returns:
- (
EINA_TRUE
= success,EINA_FALSE
= error)
For example, freedesktop.org defines standard icon names such as "home", "network", 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. One can change the lookup order with elm_icon_order_lookup_set().
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 elm_image_file_set().
Referenced by elm_menu_item_icon_name_set(), and elm_photo_file_set().
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.
- Parameters:
-
obj The icon object file The path to file that will be used as icon image group The group that the icon belongs to an edje file
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.
