XDrawRectangle(3X11)    COMMAND REFERENCE    XDrawRectangle(3X11)



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]

     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.
