NAME

       XmbDrawText, XwcDrawText, Xutf8DrawText - draw text using multiple font sets

SYNTAX

       void XmbDrawText(Display *display, Drawable d, GC gc, int x, int y, XmbTextItem *items, int nitems);

       void XwcDrawText(Display *display, Drawable d, GC gc, int x, int y, XwcTextItem *items, int nitems);

       void Xutf8DrawText(Display *display, Drawable d, GC gc, int x, int y, XmbTextItem *items, int nitems);

ARGUMENTS

       d         Specifies the drawable.

       display   Specifies the connection to the X server.

       gc        Specifies the GC.

       items     Specifies an array of text items.

       nitems    Specifies the number of text items in the array.

       x
       y         Specify the x and y coordinates.

DESCRIPTION

       The  XmbDrawText,  XwcDrawText  and  Xutf8DrawText  functions  allow  complex spacing and font set shifts
       between text strings.  Each text item is processed in turn, with the origin of a text element advanced in
       the primary draw direction by the escapement of the previous text item.  A text item delta  specifies  an
       additional  escapement  of the text item drawing origin in the primary draw direction.  A font_set member
       other than None in an item causes the font set to be used for this  and  subsequent  text  items  in  the
       text_items list.  Leading text items with a font_set member set to None will not be drawn.

       XmbDrawText,  XwcDrawText  and  Xutf8DrawText do not perform any context-dependent rendering between text
       segments.  Clients may compute the drawing metrics  by  passing  each  text  segment  to  XmbTextExtents,
       XwcTextExtents,       Xutf8TextExtents       or       XmbTextPerCharExtents,       XwcTextPerCharExtents.
       Xutf8TextPerCharExtents.  When the XFontSet has missing charsets, each  unavailable  character  is  drawn
       with the default string returned by XCreateFontSet.  The behavior for an invalid codepoint is undefined.

       The  function  Xutf8DrawText  is  an  extension  introduced  by The XFree86 Project, Inc., in their 4.0.2
       release.  Its presence is indicated by the macro X_HAVE_UTF8_STRING.

STRUCTURES

       The XmbTextItem structure contains:
       typedef struct {
               char *chars;    /* pointer to string */
               int nchars;     /* number of bytes */
               int delta;      /* pixel delta between strings */
               XFontSet font_set;      /* fonts, None means don't change */
       } XmbTextItem;
       The XwcTextItem structure contains:
       typedef struct {
               wchar_t *chars; /* pointer to wide char string */
               int nchars;     /* number of wide characters */
               int delta;      /* pixel delta between strings */
               XFontSet font_set;      /* fonts, None means don't change */
       } XwcTextItem;
