## Detailed Description

Functions that operate on single line, single style text objects.

For multiline and multiple style text, see Textblock Object Functions.

See some examples on this group of functions.

Warning
  We don't guarantee any proper results if you create a Text object without setting the evas engine.

## Macro Definition Documentation

## ◆ EVAS_TEXT_STYLE_BASIC_SET

#define EVAS_TEXT_STYLE_BASIC_SET | ( |  | x,
|  |  | s
| ) |  | do { x = ((x) & ~EVAS_TEXT_STYLE_MASK_BASIC) | (s); } while (0)

Text style type creation macro.

Use style types on the 's' arguments, being 'x' your style variable.

## ◆ EVAS_TEXT_STYLE_SHADOW_DIRECTION_SET

#define EVAS_TEXT_STYLE_SHADOW_DIRECTION_SET | ( |  | x,
|  |  | s
| ) |  | do { x = ((x) & ~EVAS_TEXT_STYLE_MASK_SHADOW_DIRECTION) | (s); } while (0)

Text style type creation macro.

This one will impose shadow directions on the style type variable – use the `EVAS_TEXT_STYLE_SHADOW_DIRECTION_*` values on 's', incrementally.

## Enumeration Type Documentation

## ◆ Evas_Text_Style_Type

enum Evas_Text_Style_Type

Types of styles to be applied on text objects.

The EVAS_TEXT_STYLE_SHADOW_DIRECTION_* ones are to be OR'ed together with others imposing shadow, to change the shadow's direction.

EVAS_API void evas_object_text_font_source_set | ( | Eo * | obj,
|  | const char * | font_source
| ) |  |

This function allows the font file to be explicitly set for a given text object, overriding system lookup, which will first occur in the given file's contents.

See also
  evas_object_text_font_get()

Parameters

  [in] | font_source | The font file's path.

## ◆ evas_object_text_font_source_get()

Get the font file's path which is being used on a given text object.

Returns
  The font file's path.

## ◆ evas_object_text_font_set()

EVAS_API void evas_object_text_font_set | ( | Eo * | obj,
|  | const char * | font,
|  | Evas_Font_Size | size
| ) |  |

Set the font family or filename, and size on a given text object.

This function allows the font name and size of a text object to be set. The `font` string has to follow fontconfig's convention on naming fonts, as it's the underlying library used to query system fonts by Evas (see the `fc-list` command's output, on your system, to get an idea). Alternatively, one can use a full path to a font file.

  evas_object_text_font_get()
  evas_object_text_font_source_set()

Parameters

  [in] | font | The font family name or filename.
  [in] | size | The font size, in points.

## ◆ evas_object_text_font_get()

EVAS_API void evas_object_text_font_get | ( | const Eo * | obj,
|  | const char ** | font,
|  | Evas_Font_Size * | size
| ) |  |

Retrieve the font family and size in use on a given text object.

This function allows the font name and size of a text object to be queried. Be aware that the font name string is still owned by Evas and should not have free() called on it by the caller of the function.

Parameters

  [out] | font | The font family name or filename.
  [out] | size | The font size, in points.
