Tk_GetVRootGeometry(3)Tk Library ProceduresTk_GetVRootGeometry(3)_________________________________________________________________NAMETk_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.
