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 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.
