Enums
-
enum lv_text_flag_t

-
enumerator LV_TEXT_FLAG_NONE
-
enumerator LV_TEXT_FLAG_EXPAND
Ignore max-width to avoid automatic word wrapping
-
enumerator LV_TEXT_FLAG_FIT
Max-width is already equal to the longest line. (Used to skip some calculation)
-
enumerator LV_TEXT_FLAG_BREAK_ALL
To prevent overflow, insert breaks between any two characters. Otherwise breaks are inserted at word boundaries, as configured via LV_TXT_BREAK_CHARS or according to LV_TXT_LINE_BREAK_LONG_LEN, LV_TXT_LINE_BREAK_LONG_PRE_MIN_LEN, and LV_TXT_LINE_BREAK_LONG_POST_MIN_LEN.

Functions
-
void lv_text_get_size(lv_point_t *size_res, const char *text, const lv_font_t *font, int32_t letter_space, int32_t line_space, int32_t max_width, lv_text_flag_t flag)
Get size of a text
line breaks
- Parameters:
size_res -- pointer to a 'point_t' variable to store the result
text -- pointer to a text
font -- pointer to font of the text
letter_space -- letter space of the text
line_space -- line space of the text
max_width -- max width of the text (break the lines to fit this size). Set COORD_MAX to avoid
flag -- settings for the text from lv_text_flag_t
-
int32_t lv_text_get_width(const char *txt, uint32_t length, const lv_font_t *font, int32_t letter_space)
Give the length of a text with a given font
- Parameters:
txt -- a '\0' terminate string
length -- length of 'txt' in byte count and not characters (Á is 1 character but 2 bytes in UTF-8)
font -- pointer to a font
