gc\^, int x\^, int y\^, XmbTextItem *items\^, int
nitems\^);
void XwcDrawText\^(\^Display *display\^, Drawable d\^, GC

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
and
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
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
will not be drawn.
and
do not perform any context-dependent rendering between text segments.
Clients may compute the drawing metrics by passing each text segment to
or
When the
has missing charsets, each unavailable character is drawn
with the default string returned by
The behavior for an invalid codepoint is undefined.
The function
is an extension introduced by The XFree86 Project, Inc. in their 4.0.2
release. Its presence is
indicated by the macro
STRUCTURES
The
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
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;
