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. 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.
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.
