Tk_GetRootCoords(3)	     Tk Library Procedures	   Tk_GetRootCoords(3)

______________________________________________________________________________

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_Get‐
       RootCoords returns the root-window coordinates corresponding  to	 loca‐
       tion  (0,0)  in tkwin.  Tk_GetRootCoords is relatively efficient, since
       it does not have to communicate with the X server.

KEYWORDS
       coordinates, root window
