XmbDrawText(3)            XLIB FUNCTIONS           XmbDrawText(3)



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 mem-
       ber 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, Xutf8Tex-
       tExtents 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;
