Tk_GetVRootGeometry(3Tk)Tk_GetVRootGeometry(3Tk)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 virtual root.
int heightPtr (out) Points to word in which to store height|
of virtual root.
DESCRIPTION
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.
