XDrawRectangle(3X) XDrawRectangle(3X)
NAME
XDrawRectangle, XDrawRectangles - draw rectangles
SYNOPSIS
XDrawRectangle(display, d, gc, x, y, width, height)
Display *display;
Drawable d;
GC gc;
int x, y;
unsigned int width, height;
XDrawRectangles(display, d, gc, rectangles,
nrectangles)
Display *display;
Drawable d;
GC gc;
XRectangle rectangles[];
int nrectangles;
ARGUMENTS
d Specifies the drawable.
display Specifies the connection to the X server.
gc Specifies the GC.
nrectangles
Specifies the number of rectangles in the
array.
rectangles
Specifies a pointer to an array of
rectangles.
width
height Specify the width and height, which specify
the dimensions of the rectangle.
x
y Specify the x and y coordinates, which
specify the upper-left corner of the
rectangle.
DESCRIPTION
The XDrawRectangle and XDrawRectangles functions draw
the outlines of the specified rectangle or rectangles
as if a five-point PolyLine protocol request were
specified for each rectangle:
[x,y] [x+width,y] [x+width,y+height] [x,y+height]
[x,y]

XDrawRectangle(3X) XDrawRectangle(3X)
For the specified rectangle or rectangles, these
functions do not draw a pixel more than once.
XDrawRectangles draws the rectangles in the order
listed in the array. If rectangles intersect, the
intersecting pixels are drawn multiple times.
Both functions use these GC components: function,
plane-mask, line-width, line-style, join-style, fill-
style, 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, tile-stipple-y-origin, dash-
offset, and dash-list.
XDrawRectangle and XDrawRectangles 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.
