Function Documentation

change_fonto_utf8()

void change_fonto_utf8	(	utf8_str *	pstr,
		enum font_origin	origin
	)

Change font size of text to that from given origin.

Definition at line 585 of file gui_string.c.

change_ptsize_utf8()

void change_ptsize_utf8	(	utf8_str *	pstr,
		Uint16	new_ptsize
	)

Change font size of text.

Definition at line 560 of file gui_string.c.

convert_utf8_str_to_const_surface_width()

bool convert_utf8_str_to_const_surface_width	(	utf8_str *	pstr,
		int	width
	)

Wrap text to make it fit to given screen width.

Definition at line 450 of file gui_string.c.

copy_chars_to_utf8_str()

utf8_str * copy_chars_to_utf8_str	(	utf8_str *	pstr,
		const char *	pchars
	)

Convert char array to utf8_str. Pointer to target string is needed as parameter, but also returned for convenience.

Definition at line 249 of file gui_string.c.

create_text_surf_from_utf8()

SDL_Surface * create_text_surf_from_utf8

(

utf8_str *

pstr

)

Generic function to create surface with any kind of text, single line or multiline, drawn.

Definition at line 426 of file gui_string.c.

create_text_surf_smaller_than_w()

SDL_Surface * create_text_surf_smaller_than_w	(	utf8_str *	pstr,
		int	w
	)

Create surface with text drawn to it. Wrap text as needed to make it fit in given width.

Definition at line 540 of file gui_string.c.

create_utf8_multi_surf()

static SDL_Surface * create_utf8_multi_surf ( utf8_str *  pstr )

static

Create surface with multiline text drawn.

Definition at line 343 of file gui_string.c.

create_utf8_str()

utf8_str * create_utf8_str	(	char *	in_text,
		size_t	n_alloc,
		Uint16	ptsize
	)

Create utf8_str struct with ptsize font. If ptsize is zero, use theme's default font size.

Font will be loaded or aliased with existing font of that size. in_text must be allocated in memory (fc_malloc() / fc_calloc())

Definition at line 204 of file gui_string.c.

create_utf8_str_fonto()

utf8_str * create_utf8_str_fonto	(	char *	in_text,

		enum font_origin	origin
	)

Create utf8_str struct with font size from given origin.

Font will be loaded or aliased with existing font of that size. in_text must be allocated in memory (fc_malloc() / fc_calloc())

Definition at line 239 of file gui_string.c.
