Detailed Description

Functions that deal with Text Classes.

Sometimes we want to change the text of two or more parts equally and that's when we use text classes.

If one or more parts are assigned with a text class, when we set font attributes to this class will update all these parts with the new font attributes. Setting values to a text class at a process level will affect all parts with that text class, while at object level will affect only the parts inside an specified object.

Function Documentation

◆ edje_text_class_set()

Eina_Bool edje_text_class_set ( const char *  text_class,
const char *  font,
Evas_Font_Size  size 
)

Sets the Edje text class.

Parameters
text_classThe text class name
fontThe font name
sizeThe font size
Returns
EINA_TRUE on success, or EINA_FALSE on error

This function updates all Edje members at the process level which belong to this text class with the new font attributes. If the size is 0 then the font size will be kept with the previous size. If the size is less then 0 then the font size will be calculated in the percentage. For example, if the size is -50, then the font size will be scaled to half of the original size and if the size is -10 then the font size will be scaled as much as 0.1x.

◆ edje_text_class_get()

Eina_Bool edje_text_class_get ( const char *  text_class,
const char **  font,
Evas_Font_Size size 
)

Gets the font and the font size from Edje text class.

Parameters
text_classThe text class name
fontThe font name
sizeThe font size
Returns
EINA_TRUE on success, or EINA_FALSE on error

This function gets the font and the font name from the specified Edje text class. The font string will only be valid until the text class is changed or edje is shut down.

◆ edje_text_class_del()

void edje_text_class_del ( const char *  text_class)

Deletes the text class.

Parameters
text_classThe text class name string

This function deletes any values at the process level for the specified text class.

◆ edje_text_class_list()

Eina_List * edje_text_class_list ( void  )

Lists text classes.

Returns
A list of text class names (strings). These strings are stringshares and the list must be free()'d by the caller.

This function lists all text classes known about by the current process.

References eina_hash_foreach().

◆ edje_text_class_active_iterator_new()

Eina_Iterator * edje_text_class_active_iterator_new ( void  )

Iterate over all active classes of an application.

Returns
an iterator of Edje_Text_Class of the currently active text class

This function only iterates over the Edje_Text_Class in use by an application.

Since
1.17

References EINA_MAGIC_SET.

◆ edje_mmap_text_class_iterator_new()

Eina_Iterator * edje_mmap_text_class_iterator_new ( Eina_File f)

Iterate over all text classes provided by an Edje file.

Parameters
fThe mapped edje file.
Returns
an iterator of Edje_Text_Class provided by the Edje file.
Since
1.17

◆ edje_object_text_class_set()

Eina_Bool edje_object_text_class_set ( Evas_Object obj,
const char *  text_class,
const char *  font,
Evas_Font_Size  size 
)

Sets Edje text class.

This function sets the text class for the Edje.

Parameters
[in]text_classThe text class name
[in]fontFont name
[in]sizeFont Size
Returns
true, on success or false, on error

◆ edje_object_text_class_get()

Eina_Bool edje_object_text_class_get ( const Evas_Object obj,
const char *  text_class,
const char **  font,
Evas_Font_Size size 
)

Gets font and font size from edje text class.

This function gets the font and the font size from the object text class. The font string will only be valid until the text class is changed or the edje object is deleted.

Parameters
[in]text_classThe text class name
[out]fontFont name
[out]sizeFont Size
Returns
true, on success or false, on error

◆ edje_object_text_class_del()

void edje_object_text_class_del ( Evas_Object obj,
const char *  text_class 
)

Delete the object text class.

This function deletes any values at the object level for the specified object and text class.

Deleting the text class will revert it to the values defined by edje_text_class_set() or the text class defined in the theme file.

Parameters
[in]text_classThe color class to be deleted.
Since
1.17

◆ edje_file_text_class_set()

Eina_Bool edje_file_text_class_set ( const char *  file,
const char *  text_class,
const char *  font,
Evas_Font_Size  size 
)

Sets Edje text class for edje file (if loaded)

This function sets the text class for All Edje Objects created from Edje file. (if edje file loaded before)

Parameters
