XTranslateCoordinates - translate window coordinates
Bool XTranslateCoordinates(Display *display, Window src_w,
dest_w, int src_x, int src_y, int *dest_x_return, int
*dest_y_return, Window *child_return);
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 destina-
tion 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.
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. Other-
wise, child_return is set to None.
XTranslateCoordinates can generate a BadWindow error.
BadWindow A value for a Window argument does not name a
defined Window.
