.SH NAME
Tk_GetRootCoords \- Compute root-window coordinates of window
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR
.sp
\fBTk_GetRootCoords\fR(\fItkwin, xPtr, yPtr\fR)
.SH ARGUMENTS
.AS Tk_Window tkwin
.AP Tk_Window tkwin in
Token for window.
.AP int *xPtr out
Pointer to location in which to store root-window x-coordinate
corresponding to left edge of \fItkwin\fR's border.
.AP int *yPtr out
Pointer to location in which to store root-window y-coordinate
corresponding to top edge of \fItkwin\fR's border.
.BE

.SH DESCRIPTION
.PP
This procedure scans through the structural information maintained
by Tk to compute the root-window coordinates corresponding to
the upper-left corner of \fItkwin\fR's border.  If \fItkwin\fR has
no border, then \fBTk_GetRootCoords\fR returns the root-window
coordinates corresponding to location (0,0) in \fItkwin\fR.
\fBTk_GetRootCoords\fR is relatively efficient, since it doesn't have to
communicate with the X server.

.SH KEYWORDS
coordinates, root window
