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.

See also:: evas_object_text_font_set()

Parameters:

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

Since :: 2.3.1

Examples:: evas-text.c.

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.

See also:: 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.

const char* evas_object_text_font_source_get ( const Eo * obj )

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

Returns:: The font file's path.

See also:: evas_object_text_font_get() for more details

Since :: 2.3.1

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

Set the font (source) file to be used on a given text object.

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.

Since :: 2.3.1
