NAME

Tk_GetRootCoords - Compute root-window coordinates of window  

SYNOPSIS

#include <tk.h>

Tk_GetRootCoords(tkwin, xPtr, yPtr)
 

ARGUMENTS

Tk_Window    tkwin    (in)
Token for window.
int    *xPtr    (out)
Pointer to location in which to store root-window x-coordinate corresponding to left edge of tkwin's border.
int    *yPtr    (out)
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_GetRootCoords returns the root-window coordinates corresponding to location (0,0) in tkwin. Tk_GetRootCoords is relatively efficient, since it doesn't have to communicate with the X server.
