XwcDrawText()															     XwcDrawText()

Name
  XwcDrawText - draw internationalized wide-character text using multiple font sets.

Synopsis
  void XwcDrawText(display, drawable, gc, x, y, items, nitems)
	Display *display;
	Drawable drawable;
	GC gc;
	int x, y;
	XwcTextItem *items;
	int nitems;

Arguments
  display   Specifies the connection to the X server.

  drawable  Specifies the drawable.

  gc	    Specifies the graphics context.

  x, y	    Specifies the starting position and baseline of the text, relative to the origin of the specified drawable.

  items     Specifies an array of text items.

  nitems    Specifies the number of text items in the array.

Availability
  Release 5 and later.

Description
  XwcDrawText()  allows  complex  spacing and font set shifts between wide-character 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  speci-
  fies	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 items list.	Leading text items with font_set member set  to  None
  will not be drawn.

  XwcDrawText()  does  not perform any context-dependent rendering between text segments.  Clients may compute the drawing metrics by passing
  each text segment to XwcTextExtents() or XmbTextPerCharExtents().  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.

  XwcDrawText()  draws	with  fonts  from the font sets of the items list rather than the font of the GC.  For this reason, it may modify the
  font value of the GC.  Except for the font, it uses the same GC components as its pre-X11R5 analog XDrawText().

Structures
  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;

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, XwcTextPer-
       CharExtents.  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;
