Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr, heightPtr)
ARGUMENTS
Tk_Window tkwin
(in) int xPtr
(out) int yPtr
(out) "int" widthPtr
(out) "int" heightPtr
(out)
TkGetVRootGeometry returns geometry information about the virtual
root window associated with tkwin. The ``associated'' 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.
