XDrawText(3X11)         COMMAND REFERENCE         XDrawText(3X11)



NAME
     XDrawText, XDrawText16 - draw polytext text

SYNOPSIS
     XDrawText(display, d, gc, x, y, items, nitems)
           Display *display;
           Drawable d;
           GC gc;
           int x, y;
           XTextItem *items;
           int nitems;

     XDrawText16(display, d, gc, x, y, items, nitems)
           Display *display;
           Drawable d;
           GC gc;
           int x, y;
           XTextItem16 *items;
           int nitems;

ARGUMENTS
     d         Specifies the drawable.

     display   Specifies the connection to the X server.

     gc        Specifies the GC.

     items     Specifies a pointer to an array of text items.

     nitems    Specifies the number of text items in the array.

     x
     y         Specify the x and y coordinates, which are
               relative to the origin of the specified drawable
               and define the origin of the first character.

DESCRIPTION
     The XDrawText16 function is similar to XDrawText except that
     it uses 2-byte or 16-bit characters.  Both functions allow
     complex spacing and font shifts between counted strings.

     Each text item is processed in turn.  A font member other
     than None in an item causes the font to be stored in the GC
     and used for subsequent text. A text element delta specifies
     an additional change in the position along the x axis before
     the string is drawn. The delta is always added to the
     character origin and is not dependent on any characteristics
     of the font.  Each character image, as defined by the font
     in the GC, is treated as an additional mask for a fill
     operation on the drawable.  The drawable is modified only
     where the font character has a bit set to 1.  If a text item
     generates a BadFont error, the previous text items may have

     been drawn.

     For fonts defined with linear indexing rather than 2-byte
     matrix indexing, each XChar2b structure is interpreted as a
     16-bit number with byte1 as the most-significant byte.

     Both functions use these GC components: function, plane-
     mask, fill-style, font, subwindow-mode, clip-x-origin,
     clip-y-origin, and clip-mask.  They also use these GC mode-
     dependent components: foreground, background, tile, stipple,
     tile-stipple-x-origin, and tile-stipple-y-origin.

     XDrawText and XDrawText16 can generate BadDrawable, BadFont,
     BadGC, and BadMatch errors.

DIAGNOSTICS
     BadDrawable
               A value for a Drawable argument does not name a
               defined Window or Pixmap.

     BadFont   A value for a Font or GContext argument does not
               name a defined Font.

     BadGC     A value for a GContext argument does not name a
               defined GContext.

     BadMatch  An InputOnly window is used as a Drawable.
