让 Zenity 对话框始终位于前台顶部

有没有办法检测对话框Zenity是否失去焦点？

我想将对话框保留在前台，除非用户按下ESC。

我正在尝试将其添加到这个脚本:

#!/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

答案1

#!/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")

如果将其作为 cron 作业运行，则可能会遇到问题。 Cron 的环境不知道您的 X 显示、dbus 或桌面，并且不会显示 zenity 框或将其保留在顶部。在之前添加 DISPLAY=:0两个都wmctrl 和 zenity 解决了该问题：

(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")

此解决方案与@Jan 的解决方案基本相同，但使用 PID 而不是窗口标题来识别窗口，此外与 Bourne Shell 兼容（-> 不需要 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 $!
