XLIB FUNCTIONS                                  XmbDrawText(3x11)



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

SYNTAX
     cc [ flag... ] file... -lX11 [ library... ]

     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 ori-
     gin 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;
