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 corre-sponding corresponding
                                     sponding to left edge of tkwin's border.

       int         *yPtr   (out)     Pointer to location in which to store root-window  y-coordinate  corre-sponding corresponding
                                     sponding 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 doesn't have to communicate with the X server.


KEYWORDS
       coordinates, root window
