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

       Tk_GetVRootGeometry  returns geometry information about the virtual root window associated
       with tkwin.  The “associated” 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 does not 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.
