.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.
