App-icon missing on linux

[yafp]

Operating system

• Ubuntu Linux -

Application

• Desktop 0.10.38

The app is not showing any specific application icon in my panel. Instead a default/generic application icon is displayed.

The android app has an app-icon, therefor i assume it is not just the fact that there is no logo designed yet.

This is still valid for me with 0.10.39 on Ubuntu, running gnome-shell.

If i search for joplin the blue icon is displayed in the search results, but not in the dock (using Gnome Shell extension Dash-to-Dock) itself.

Same is happening to me, using latest (1.0.64) AppImage. The application icon is shown in the picture below:

This is the application icon when I search for it:

I am using:

• Ubuntu x64 16.04.3 LTS
• Paper icon theme
• Gnome-shell 3.18.5

May be related to #251 or be linux-specific

Hi,

Firstly, thank you for an amazing project.

You may be able to resolve this by calling "QApplication::setWindowIcon()" in Joplin.

You can see a write-up for a similar issue for another application here: https://discourse.appimage.org/t/appimage-does-not-show-icon-in-task-bar/40

There is also another approach that seems to work:

electron-userland/electron-builder#2269 (see the last post)

Hopefully either of these approaches provide a reasonably straight forward fix for the Linux icon issue.

Thanks again for the wonderful work.

Regards...

If you edit the appimagekit-joplin.desktop file (located in ~/.local/share/applications) and add

StartupWMClass=Joplin

to it then the icon is displayed in Gnome3.

@StefanTT This worked as a workaround for me.

Is there any chance that this happens due to some kind of config conflict on Gnome-Shell? My version is 3.18.5 by the way.

I wonder if with the new Ubuntu 18.04 LTS coming next month this will still happen. May be Gnome-Shell related.

[StefanTT]

If I look at the generated .desktop entry and what xprop for the Joplin window outputs then I have no good idea how the window manager should get the icon for the application.

A quick test with TeamViewer - one of the apps I have installed that did not come with the distribution - showed that they do not set StartupWMClass in the desktop entry but set the window property WM_ICON_NAME.

So either the setWindowIcon() that @blueorignal suggested or my workaround should be done. I doubt that other desktop environments currently find the correct icon.

Thank you @StefanTT !
This worked also for Linux Mint 19 with Cinnamon 3.8.8

@laurent22 Today evening (CET) electron-builder 20.26.0 will be released — StartupWMClass will be added correctly (thanks to @StefanTT). So, you can just update electron-builder version to upcoming 20.26.0 and this issue will be fixed.

@StefanTT workaround worked for me to in Ubuntu 18.04

[scollovati]

Actually today after reinstalling my OS (a clean install) I'm experiencing a problem with the tray icon

I manually added the suggested line to the .desktop file.
Still using Linux Mint 19 with Cinnamon 3.8.8, Kernel 4.15.0-20-generic

[laurent22]

Should be fixed with recently added install_ubuntu.sh script.

I just experienced this with a fresh install of Joplin on a new 18.10 ubuntu install. @StefanTT 's fix worked though.
