### window

A window object specifies size, position, and other window-system related information about a window in a device-independent way.

The syntax for a window object is:

    window ::=

    	[ "window" ]			(optional keyword)
    	  [ "{" ]			(curly brace, often required)

    	    			(any of the following, in any order)

    		"size"  <xsize> <ysize>
    				(size of the window)

    		"position"  <xmin> <xmax> <ymin> <ymax>
    				(position & size)

    		"noborder"
    				(specifies the window should
    				 have no window border)

    		"pixelaspect"  <aspect>
    			    (specifies the true visual aspect ratio
    			     of a pixel in this window in the sense
    			     xsize/ysize, normally 1.0.
    			     For stereo hardware which stretches the
    			     display vertically by a factor of 2,
    			     ``pixelaspect 0.5'' might do.
    			     The value is used when computing the
    			     projection of a camera associated with
    			     this window.)

    	  [ "}" ]			(matching closebrace)

Window objects are used in the Geomview `window` and `ui-panel` commands to set default properties for future windows or to change those of an existing window.
