Mantieni una finestra di dialogo Zenity sempre in primo piano

C'è un modo per rilevare che una Zenityfinestra di dialogo ha perso la concentrazione?

Vorrei mantenere la finestra di dialogo in primo piano a meno che l'utente non prema ESC.

Sto tentando di aggiungerlo a questo script :

#!/bin/bash

# requires these packages from ubuntu repository:
# wmctrl, zenity, x11-utils 
# and the script mouse-speed

# This procect on git:        https://github.com/rubo77/mouse-speed


######## configuration ##########
# seconds between micro breaks
microbreak_time=$(( 10 * 60 ))
# micro break duration in seconds
microbreak_duration=15
# seconds between long breaks
longbreak_time=$(( 120 * 60 ))

# message to display 
message="Try focussing a far object outside the window with the eye to relax!"
longbreak_message="Change your seating or continue work in a standing/sitting position"
#postpone label
postpone="Postpone"

window_title="typebreak"

# global zoom of your window manager:
ZOOM=2
# height in px of the top system-bar:
TOPMARGIN=57
# sum in px of all horizontal borders:
HORIZONTALMARGIN=40
# get width of screen and height of screen
SCREEN_WIDTH=$(xwininfo -root | awk '$1=="Width:" {print $2}')
SCREEN_HEIGHT=$(xwininfo -root | awk '$1=="Height:" {print $2}')
# width and height
W=$(( $SCREEN_WIDTH / $ZOOM - 2 * $HORIZONTALMARGIN ))
H=$(( $SCREEN_HEIGHT / $ZOOM - 2 * $TOPMARGIN ))

function slow_down(){
    #zenity --warning --text "slow down mouse";
    mouse-speed -d 30
}

while true; do
    # short loop every few minutes to look around
    sleep $microbreak_time
    (
    echo "99"
    sleep $(( $microbreak_duration - 2 ))
    echo "# Mouse speed reset to 100%"
    sleep 2
    echo "100"
    ) | if ( sleep 1 && wmctrl -F -a "$window_title" -b add,maximized_vert,maximized_horz && sleep 3 &&  wmctrl -F -a "$window_title" -b add,above ) & ( zenity --progress --text "$message" --percentage=0 --auto-close  --height=$H --width=$W --pulsate --title="$window_title" --cancel-label="$postpone" ); then
        #zenity --info --text "Maus normal speed!"
        mouse-speed -r
    else 
        slow_down
    fi
done &
while true; do
    # second long loop to change seat position
    sleep $longbreak_time
    zenity --warning --text "$longbreak_message" --title="$window_title - long break"
done

#!/bin/bash
# This will wait one second and then steal focus and make the Zenity dialog box always-on-top (aka. 'above').

(sleep 1 && wmctrl -F -a "I am on top" -b add,above) &
(zenity --info --title="I am on top" --text="How to help Zenity to get focus and be always on top")

Potresti incorrere in problemi se lo esegui come cron job. L'ambiente di Cron non è a conoscenza del display X, del dbus o del desktop e non visualizzerà il box zenity né lo manterrà in primo piano. L'aggiunta di DISPLAY =: 0 prima sia di wmctrl che di zenity risolve il problema:

(sleep 1 && DISPLAY=:0 wmctrl -F -a "I am on top" -b add,above) & (DISPLAY=:0 zenity --info --title="I am on top" --text="How to help Zenity to get focus and be always on top")

Questa soluzione è per lo più identica a quella di @Jan, ma utilizza il PID anziché il titolo della finestra per identificare la finestra e inoltre è compatibile con Bourne Shell (-> non richiede bash).

#!/bin/sh
# This will wait 200ms, steal focus and set the Zenity dialog box
# to "always-on-top".

modify_win_by_pid() {
    pid=$1

    sleep 0.2
    win_id=`wmctrl -l -p | grep ${pid} | awk '{print $1}'`
    wmctrl -i - ${win_id} -b add,above
}

zenity --info --title="I am on top" --text="I received focus and will stay on top" &
modify_win_by_pid $!
