xcb_image_text_8(3) XCB Requests xcb_image_text_8(3)
NAME
xcb_image_text_8 - Draws text
SYNOPSIS
#include <xcb/xproto.h>
Request function
xcb_void_cookie_t xcb_image_text_8(xcb_connection_t *conn,
uint8_t string_len, xcb_drawable_t drawable, xcb_gcontext_t gc,
int16_t x, int16_t y, const char *string);
REQUEST ARGUMENTS
conn The XCB connection to X11.
string_len
The length of the string. Note that this parameter 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.
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_8_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?
