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 virtual root.

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

DESCRIPTION

       Tk_GetVRootGeometry  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 does not 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.
