## 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 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

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