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 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 does not have to commu- nicate with the X server. KEYWORDS coordinates, root window Tk Tk_GetRootCoords(3)
