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);
Specifies the drawable.
Specifies the connection to the X server.
Specifies the GC.
Specifies the number of characters in the string argument.
Specifies the character string. and define the origin of the first character
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.
