Get current window title in bash

[Иванов Дмитрий]

My goal is to print the current window title in bash prompt. Currently I
know $WINDOW environment variable that contains the number of the
currently selected window.

I learned about "screen -Q title" command but 2 problems emerged:

1. This command is slow and makes a delay when used in .bashrc.
2. When I tried this code:

if [ -n "$STY" ]; then
    TITLE=$(screen -Q title)
    PS1=$PS1"\[\033[01;93m\]$TITLE "
fi

It shows the title in the prompt and I have to click extra Enter key. Is
it possible to get the name quickly?
