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 vir
tual root.
int heightPtr (out) Points to word in which
to store height of vir
tual root.

DESCRIPTION
TkGetVRootGeometry returns geometry information about the
virtual root window associated with tkwin. The ``associ
ated'' 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 doesn't 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.
