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;
