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
- 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.
