.SH ARGUMENTS
.IP \fIchild_return\fP 1i
Returns the child if the coordinates are contained in a mapped child of the
destination window.
.IP \fIdest_w\fP 1i
Specifies the destination window.
.IP \fIdest_x_return\fP 1i
.br
.ns
.IP \fIdest_y_return\fP 1i
Return the x and y coordinates within the destination window.
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIsrc_w\fP 1i
Specifies the source window.
.IP \fIsrc_x\fP 1i
.br
.ns
.IP \fIsrc_y\fP 1i
Specify the x and y coordinates within the source window.
.SH DESCRIPTION
If
.B XTranslateCoordinates
returns
.BR 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
.B XTranslateCoordinates
returns
.BR 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
.BR None .
.LP
.B XTranslateCoordinates
can generate a
.B BadWindow
error.
.SH DIAGNOSTICS
.TP 1i
.B BadWindow
A value for a Window argument does not name a defined Window.
