XDrawString, XDrawString16
- draw text characters
- 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);
- 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.
- x
- y
- Specify the x and y coordinates, which are relative to the origin of
the specified drawable and define the origin of the first character.
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.
- 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.
