Re: Screen title, not just $WINDOW number, in prompt?

I just include $WINDOW (which is defined in the environment by screen)
in bash's PS1 (prompt) variable.  E.g.,

if test x"$WINDOW" != x""; then
  SCREEEN_PS1="($WINDOW)"
else
  SCREEEN_PS1=""
fi
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;address@hidden:\[\033[01;34m\]\w\[\033[00m\]${SCREEEN_PS1}\$

'

This results in the prompt looking like (for screen window 1):

address@hidden:~(1)$

What I want to do is instead of it showing the number of the screen, to
have it show the title I've assigned that window via C-a A.  All I need
in order to do this is to know how to access that information from
screen given the $WINDOW number (I can use bash's $PROMPT_COMMAND to set
PS1 dynamically).  E.g.,:

address@hidden:~(compile)$

I played around with this but couldn't seem to get it to react - is this
for setting the title in an xterm?
