xcb_image_text_16(3) XCB Requests xcb_image_text_16(3)
NAME
xcb_image_text_16 - Draws text
SYNOPSIS
#include <xcb/xproto.h>
Request function
xcb_void_cookie_t xcb_image_text_16(xcb_connection_t *conn,
uint8_t string_len, xcb_drawable_t drawable, xcb_gcontext_t gc,
int16_t x, int16_t y, const xcb_char2b_t *string);
REQUEST ARGUMENTS
conn The XCB connection to X11.
string_len
The length of the string in characters. Note that this param-
eter limited by 255 due to using 8 bits!
drawable The drawable (Window or Pixmap) to draw text on.
gc The graphics context to use.
The following graphics context components are used: plane-
mask, foreground, background, font, subwindow-mode, clip-x-
origin, clip-y-origin, and clip-mask.
x The x coordinate of the first character, relative to the ori-
gin of drawable.
y The y coordinate of the first character, relative to the ori-
gin of drawable.
string The string to draw. Only the first 255 characters are rele-
vant due to the data type of string_len. Every character uses
2 bytes (hence the 16 in this request's name).
DESCRIPTION
Fills the destination rectangle with the background pixel from gc, then
paints the text with the foreground pixel from gc. The upper-left cor-
ner of the filled rectangle is at [x, y - font-ascent]. The width is
overall-width, the height is font-ascent + font-descent. The overall-
width, font-ascent and font-descent are as returned by
xcb_query_text_extents (TODO).
Note that using X core fonts is deprecated (but still supported) in fa-
vor of client-side rendering using Xft.
RETURN VALUE
Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the
event loop.
If you want to handle errors directly with xcb_request_check instead,
use xcb_image_text_16_checked. See xcb-requests(3) for details.
ERRORS
xcb_drawable_error_t
The specified drawable (Window or Pixmap) does not exist.
xcb_g_context_error_t
The specified graphics context does not exist.
xcb_match_error_t
TODO: reasons?
