NAME
XDrawString, XDrawString16 - draw text characters
SYNTAX
int
XDrawString(Display * display, Drawable d, GC gc, int
x, int y, char *string, int length);
int
XDrawString16(Display * display, Drawable d, GC gc, int
x, int y, XChar2b *string, int length);
ARGUMENTS
- d
- Specifies the drawable.
- display
- Specifies the connection to the X server.
- gc
- Specifies the GC.
- length
- Specifies the number of characters in the string
argument.
- string
- Specifies the character string. and define the origin of
the first character
- x
-
- y
- Specify the x and y coordinates, which are relative to the
origin of the specified drawable .
DESCRIPTION
Each character image, as defined by the font in the GC, is treated as an
additional mask for a fill operation on the drawable. The drawable is modified
only where the font character has a bit set to 1. For fonts defined with
2-byte matrix indexing and used with
XDrawString16, each byte is used
as a byte2 with a byte1 of zero.
Both functions use these GC components: function, plane-mask, fill-style, font,
subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use
these GC mode-dependent components: foreground, background, tile, stipple,
tile-stipple-x-origin, and tile-stipple-y-origin.
XDrawString and
XDrawString16 can generate
BadDrawable,
BadGC, and
BadMatch errors.
DIAGNOSTICS
- BadDrawable
- A value for a Drawable argument does not name a defined
Window or Pixmap.
- BadGC
- A value for a GContext argument does not name a defined
GContext.
- BadMatch
- An InputOnly window is used as a Drawable.
- BadMatch
- Some argument or pair of arguments has the correct type and
range but fails to match in some other way required by the request.
