Display *display;
Drawable d;
GC gc;
int x, y;
XmbTextItem *items;
int nitems;

ARGUMENTS

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 and XwcDrawText 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 and XwcDrawText do not perform any context-
dependent rendering between text segments. Clients may
compute the drawing metrics by passing each text segment to
XmbTextExtents and XwcTextExtents or XmbTextPerCharExtents
and XwcTextPerCharExtents. 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.
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;
