Tk_GetRootCoords(3) Tk Library Procedures Tk_GetRootCoords(3)
NAME
Tk_GetRootCoords - Compute root-window coordinates of window
SYNOPSIS
#include <tk.h>
Tk_GetRootCoords(tkwin, xPtr, yPtr)
ARGUMENTS
Token for window. Pointer to location in which to store root-window x-
coordinate corresponding to left edge of tkwin's border. Pointer to
location in which to store root-window y-coordinate corresponding to
top edge of tkwin's border.
DESCRIPTION
This procedure scans through the structural information maintained by
Tk to compute the root-window coordinates corresponding to the upper-
left corner of tkwin's border. If tkwin has no border, then Tk_Get-
RootCoords returns the root-window coordinates corresponding to loca-
tion (0,0) in tkwin. Tk_GetRootCoords is relatively efficient, since
it does not have to communicate with the X server.
KEYWORDS
coordinates, root window
