XtTranslateCoords - Man Page

#include <X11/Intrinsic.h>

void XtTranslateCoords(Widget w, Position x, Position y, Position *rootx_return, Position *rooty_return);

rootx_return

rooty_return

Returns the root-relative x and y coordinates.

x

y

Specify the widget-relative x and y coordinates.

w

Specifies the widget.

While XtTranslateCoords is similar to the Xlib XTranslateCoordinates function, it does not generate a server request because all the required information already is in the widget's data structures.
