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	subse-
       quent 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, XwcTex-
       tExtents, Xutf8TextExtents or XmbTextPerCharExtents,  XwcTextPerCharEx-
       tents.	 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;
