- .SH NAME
- Tk_GetVRootGeometry - Get location and size of virtual root for window
- .SH SYNOPSIS
- .nf
- fB#include <tk.h>fR
- .sp
- fBTk_GetVRootGeometry(fItkwin, xPtr, yPtr, widthPtr, heightPtrfB)fR
- .SH ARGUMENTS
- .AS Tk_Window heightPtr
- .AP Tk_Window tkwin in
- Token for window whose virtual root is to be queried.
- .AP int xPtr out
- Points to word in which to store x-offset of virtual root.
- .AP int yPtr out
- Points to word in which to store y-offset of virtual root.
- .AP "int" widthPtr out
- Points to word in which to store width of virtual root.
- .AP "int" heightPtr out
- Points to word in which to store height of virtual root.

- .SH DESCRIPTION
- .PP
- fBTkGetVRootGeometryfR returns geometry information about the virtual
- root window associated with fItkwinfR. The ``associated'' virtual
- root is the one in which fItkwinfR's nearest top-level ancestor (or
- fItkwinfR itself if it is a top-level window) has
- been reparented by the window manager. This window is identified by
- a fB__SWM_ROOTfR or fB__WM_ROOTfR property placed on the top-level
- window by the window manager.
- If fItkwinfR is not associated with a virtual root (e.g.
- because the window manager doesn't use virtual roots) then *fIxPtrfR and
- *fIyPtrfR will be set to 0 and *fIwidthPtrfR and *fIheightPtrfR
- will be set to the dimensions of the screen containing fItkwinfR.
- .SH KEYWORDS
- geometry, height, location, virtual root, width, window manager
