Why does a bash-zenity script has that title on Unity Panel and that icon on Unity Launcher?

rated 0 times [ 4] [ 0] / answers: 1 / hits: 1656 / 2 Years ago, fri, may 20, 2022, 12:25:33

I have this small bash script which helps use Infinality font rendering options via a more user-friendly Zenity window: http://gnomefiles.org/content/show.php/Infinality+Style+Changer?content=161984

But whenever I launch it I have this "Color Picker" title on Unity Panel together with the icon assigned for "Color Picker" utility.

I wonder why and how this is happening and how I can change it?

enter image description here

#!/bin/bash

# A simple script to provide a basic, zenity-based GUI to change Infinality Style.

# v.1.2

#

infinality_current=`cat /etc/profile.d/infinality-settings.sh | grep "USE_STYLE=" | awk -F'"' '{print $2}'`

sudo_password="$( gksudo --print-pass --message 'Provide permission to make system changes: Enter your password to start or press Cancel to quit.' -- : 2>/dev/null )"

# Check for null entry or cancellation.

if [[ ${?} != 0 || -z ${sudo_password} ]]

then

# Add a zenity message here if you want.

exit 4

fi

# Check that the password is valid.

if ! sudo -kSp '' [ 1 ] <<<"${sudo_password}" 2>/dev/null

then

# Add a zenity message here if you want.

exit 4

fi

I think the problem is that both Zenity scripts are using the same window manager class. You can check this by executing xprop and clicking on each window, respectively.

If you supply Zenity with a WMCLASS you can make sure that the dialog will always be assigned the correct .desktop launcher.

These are the steps you will have to take:

Define a window manager class for the dialog by adding --class=<WMCLASS> to the commandline., e.g.:
```
zenity --class=InfinalitySettings --width=500 --height=490 [...]
```
You can choose an arbitrary name as long as its unique and not used by any other application/script. I don't know if special characters work, but just out of caution I would stick to alphanumeric characters only.

Append the following line to the .desktop launcher:
```
StartupWMClass=InfinalitySettings
```

Here's how you could implement this in your script (I also modified a few other things):

#!/bin/bash

# A simple script to provide a basic, zenity-based GUI to change Infinality Style.

# v.1.3



# tip: use http://www.shellcheck.net/ to avoid common problems



## variables



InfinalityConfig="/etc/profile.d/infinality-settings.sh"

InfinalityCurrent="$(cat "$InfinalityConfig" | grep "USE_STYLE=" | awk -F" '{print $2}')" 

#                  ↑ "$()" is safer than ``



## dialog



# assign descriptions and other dialog elements

# makes the script easier to read



WmClass="InfinalitySettings"





TxtMain="Current <i>Infinality Style</i> is: <b>$InfinalityCurrent</b>

✔ To <i>change</i> it, select any other option below and press <b>OK</b>

✘ To <i>quit without changing</i>, press <b>Cancel</b>"



Title="Change Infinality Style"



## functions

          exit 1

    elif [[ -z "$Choice" ]]

      then

          echo "No option selected. Exiting."

          exit 0

    fi



    echo "User chose: $Choice"

}



set_style(){

    pkexec --user root sed -i "s/USE_STYLE="$InfinalityCurrent"/USE_STYLE="$Choice"/g"

     "$InfinalityConfig"

    RET_PKEXEC="$?"



    if [[ "$RET_PKEXEC" != "0" ]]

      then

          exit 1

          # Add a zenity message here if you want.

      else
