Expand description

Draws text.

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.

§Fields

  • drawable - The drawable (Window or Pixmap) to draw text on.
  • string_len - The length of the string. Note that this parameter limited by 255 due to using 8 bits!
  • string - The string to draw. Only the first 255 characters are relevant due to the data type of string_len.
  • 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.
  • 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.

§Errors

  • Drawable - The specified drawable (Window or Pixmap) does not exist.
  • GContext - The specified graphics context does not exist.
  • Match - TODO: reasons?
