Questions[zenity](ubuntu)

I'm using Kubuntu 18.04 with:

$ zenity --version
3.28.1

I want to display a --list dialog with zenity, but I don't want to show the Cancel button (in fact I'm okay if there is no OK either). It should be easy with the --no-cancel option:

$ zenity --list --no-cancel
--no-cancel is not supported for this dialog

The output seems to indicate that zenity knows about the option but does not want to let me use it.

I only want to show the user the data in a table. I don't care about selection/editing or getting a result back.

Is there any alternative way? Or is zenity simply unable to do this?

I want to make a zenity question that goes further depending on the answer you choose.

The question in my script is:

zenity --question --text="Would you like to participate in a little form?" 

_

Full script

#!/bin/bash

if [ "$(whoami)" != "root" ]; then
  echo "Put this is /sbin/ and chmod 755 it."
else
    zenity --info --text="Hi! Welcome to !!Name yet to be found!!"
    sleep 0.5
    zenity --question --text="Would you like to participate in a little form?" 
    sleep 1
    zenity --info --text="Getting important run files"
    wget 

    sleep 1
    zenity --info --text="Done!"
    sleep 1
    zenity --info --text="I will this program will move to /sbin/ and chmod 
775 it for you!
No need to thank me.
My program creator made me this way :(" 
    sudo chmod 755 ~/!!!
    mv ~/!!! /sbin/ 
    sleep 1
    zenity --info --text="Done!"
    sleep 2
    sudo xdg-open /sbin
    zenity --info --text="Well look for yourself!"
    sleep 10
    zenity --info --text="Dont rerun this file!"
    echo
    zenity --info --text="This is just the install part."
fi

How can I achieve this?

I would like the window produced by zenity to be configured so it is always on top. There does not appear to be an option to enable this. Can someone suggest a source change to the zenity code so that I can get this to work? I want to be able to do zenity --ontop "warning"

If there is an alternative which does not involve writing code, I would be interested in this too.

I found by chance it was possible to display a combo box with zenity (version tested: 2.32.1). See the following code:

#!/bin/bash
array=(a b c d e)
value=$(zenity --entry --title "Window title" --text "${array[@]}" --text "Insert your choice.")

The result is illustrated with the following 3 images:

I have two questions about that:

1. Is there a documentation about this functionality? I didn't find anything in the zenity documentation.

2. Why the first value of my array doesn't appear in the combo box? In the example above, my array is (a b c d e), and the combo box only displays b c d e.

   As a workaround, I add a value in my array, for example (0 a b c d e).

I'm having problems loading a zenity List Dialog when the data contains spaces.

It is straight-forward when there are no spaces in the listed data,
but I don't know of a simple/standard method for space-embedded file names.

For some reason, the output of $(ls -Q /tmp) (Quoted output) still
splits the file-names at every space. The quotes and back-slashes in the
ls | sed output seem to be treated as a "finalized string" rather than
as "readable data lines" (like the first two data lines)...

I've managed to "work around the issue", but Self-Modifying code probably
isn't the best way to go! (even though it is fun! :)

Here is the method which does NOT work

zenlist="/tmp/zen list"; touch "$zenlist"
zenity --list --title='A single-column List' --width=600 --height=450 \
--column='Spaces are allowed within "q u o t e s"' \
"How much wood would a woodchuck chuck," \
"if a wooodchuck could chuck wood?" \
$(ls -Q -1 "$zenlist"* |sed 's/$/ \\/')
echo ""
# rm "$zenlist"  # Uncomment this line to delete the file

This method works, but there must be a "conventional" (better) way!?

zenlist="/tmp/zen list"
echo "zenity --list --title='A single-column List' --width=600 --height=450 \\" >"$zenlist"
echo "--column='Spaces are allowed within \"q u o t e s\"' \\"       >>"$zenlist"
echo "\"How much wood would a woodchuck chuck,\" \\"       >>"$zenlist"
echo "\"if a wooodchuck could chuck wood?\" \\" >>"$zenlist"
(ls -Q "$zenlist"* |sed 's/$/ \\/')   >>"$zenlist"
echo "" >>"$zenlist"
source "$zenlist"
# rm "$zenlist"  # Uncomment this line to delete the file
