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.

KEYWORDS

coordinates, root window
