Tk_GetVRootGeometry - Get location and size of virtual root for
window
#include <tk.h>
Tk_GetVRootGeometry(tkwin, xPtr, yPtr, widthPtr,
heightPtr)
- 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.
Tk_GetVRootGeometry 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 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.
