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

Question

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?

#!/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.

The .desktop file "/usr/local/share/applications/InfinalitySettings.desktop" contains the following text:

[Desktop Entry]
Name=Infinality Style Changer
GenericName=Infinality Settings
Exec=/usr/local/bin/InfinalitySettings
Icon=gnome-settings-font
Terminal=false
Type=Application
Categories=GTK;GNOME;System;Settings;Fonts;

And here is the contents of "/usr/share/applications/zenity-color-selection.desktop" which has this title and icon:

[Desktop Entry]
Encoding=UTF-8
Type=Application
Categories=Graphics;2DGraphics;RasterGraphics;GTK;
Name=Color Picker

Icon=preferences-color
#Icon=applications-graphics
Exec=zenity --color-selection --show-palette
Terminal=false

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:

1. 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.

2. 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"

That is strange indeed. Without knowing more about where you got the script, I would have to guess. It is possible that the author has simply used the desktop file for gcolorpicker as a template for his own, simply forgetting to change the GenericName and Icon. But it is pure speculation.

If you've installed the script globally, you can look for the desktop file in /usr/share/applications. It should be called something like "infidelity-settings.desktop". If my assumption is correct, this file should contain a line like this: "GenericName=Color Picker" and another line resembling "Icon=gcolorpicker".

If you've installed the file for your user only, then you should find that desktop file in /home/yourusername/.local/share/applications/
