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:
        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;
