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 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 origin of drawable.
- y
-
The y coordinate of the first character, relative to the origin of drawable.
- string
-
The string to draw. Only the first 255 characters are relevant 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 corner 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 favor 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?
