Tk_GetVRootGeometry − Get location and size of virtual root for window
#include <tk.h>
Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr, heightPtr)
| 
 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.  |

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.
