XTranslateCoordinates(3X11)											       XTranslateCoordinates(3X11)

NAME
       XTranslateCoordinates - translate window coordinates

SYNOPSIS
       Bool XTranslateCoordinates(display, src_w, dest_w, src_x, src_y, dest_x_return, dest_y_return, child_return)
	       Display *display;
	       Window src_w, dest_w;
	       int src_x, src_y;
	       int *dest_x_return, *dest_y_return;
	       Window *child_return;

ARGUMENTS
       Returns	the child if the coordinates are contained in a mapped child of the destination window.  Specifies the destination window.  Return
       the x and y coordinates within the destination window.  Specifies the connection to the X server.  Specifies the  source  window.   Specify
       the x and y coordinates within the source window.

DESCRIPTION
       If  XTranslateCoordinates  returns  True, it takes the src_x and src_y coordinates relative to the source window's origin and returns these
       coordinates to dest_x_return and dest_y_return relative to the destination window's origin. If XTranslateCoordinates returns  False,  src_w
       and  dest_w  are  on different screens, and dest_x_return and dest_y_return are zero. If the coordinates are contained in a mapped child of
       dest_w, that child is returned to child_return. Otherwise, child_return is set to None.

       XTranslateCoordinates can generate a BadWindow error.

DIAGNOSTICS
       A value for a Window argument does not name a defined Window.
