Tk_GetVRootGeometry(3) Tk Library Procedures Tk_GetVRootGeometry(3)
NAME
Tk_GetVRootGeometry - Get location and size of virtual root for window
SYNOPSIS
#include <tk.h>
Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr, heightPtr)
ARGUMENTS
Token for window whose virtual root is to be queried. Points to word
in which to store x-offset of virtual root. Points to word in which to
store y-offset of virtual root. Points to word in which to store width
of virtual root. 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 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.
