NAME
     Tk_GetVRootGeometry - Get location and size of virtual  root
     for window

SYNOPSIS
     #include <tk.h>

     Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr, heightPtr)

ARGUMENTS
     Tk_Window   tkwin       (in)      Token  for  window   whose
                                       virtual   root  is  to  be
                                       queried.

     int         xPtr        (out)     Points to word in which to
                                       store  x-offset of virtual
                                       root.

     int         yPtr        (out)     Points to word in which to
                                       store  y-offset of virtual
                                       root.

     int         widthPtr    (out)     Points to word in which to
                                       store   width  of  virtual
                                       root.

     int         heightPtr   (out)     Points to word in which to
                                       store  height  of  virtual
                                       root.

DESCRIPTION
     TkGetVRootGeometry returns geometry  information  about  the
     virtual  root  window  associated with tkwin.  The ``associ-
     ated'' virtual root is the  one  in  which  tkwin's  nearest
     top-level  ancestor  (or  tkwin  itself if it is a top-level
     window) has been reparented by  the  window  manager.   This
     window  is  identified by a __SWM_ROOT or __WM_ROOT property
     placed on the top-level window by the  window  manager.   If
     tkwin  is  not associated with a virtual root (e.g.  because
     the window manager doesn't use virtual roots) then *xPtr and
     *yPtr  will be set to 0 and *widthPtr and *heightPtr will be
     set to the dimensions of the screen containing tkwin.


KEYWORDS
