XTranslateCoordinates(3X11)    XLIB FUNCTIONS	  XTranslateCoordinates(3X11)



NAME
  XTranslateCoordinates - translate window coordinates

SYNTAX
  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

  child_return
	    Returns the child if the coordinates are contained in a mapped
	    child of the destination window.

  dest_w    Specifies the destination window.

  dest_x_return
  dest_y_return
	    Return the x and y coordinates within the destination window.

  display   Specifies the connection to the X server.

  src_w	    Specifies the source window.

  src_x
  src_y	    Specify the x and y coordinates within the source window.

DESCRIPTION
  If XTranslateCoordinates returns True, it takes the src_x and src_y coordi-
  nates 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

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