NAME

       Tk_GetRootCoords - Compute root-window coordinates of window

SYNOPSIS

       #include <tk.h>

       Tk_GetRootCoords(tkwin, xPtr, yPtr)

ARGUMENTS

       Tk_Window tkwin (in)	     Token for window.

       int *xPtr (out)		     Pointer to location in which to store root-window x-coordinate corresponding to left edge of tkwin's border.

       int *yPtr (out)		     Pointer to location in which to store root-window y-coordinate corresponding to top edge of tkwin's border.
_________________________________________________________________

DESCRIPTION

       This procedure scans through the structural information maintained by Tk to compute the root-window coordinates corresponding to the upper-
       left corner of tkwin's border.  If tkwin has no border, then Tk_GetRootCoords returns the root-window coordinates corresponding to location
       (0,0) in tkwin.	Tk_GetRootCoords is relatively efficient, since it does not have to communicate with the X server.

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.
