Is there a way to merge an icon to an executable file?

[sokrovenno]

So, from time to time I like to log in Tibia, see how is it going and talk to old friends that still plays the game. This was the game I spent most part of my childhood playing, so it is a little nostalgic to login and see all those places that I've spent hours hunting and playing. Anyway ... To play Tibia on Linux you must download an executable file. This executable does not display the Tibia icon on xfce-panel nor on the title bar - It just shows a white box - as other programs do. Most probably it is a bug from Tibia, but I doubt they will fix it since Tibia on Linux is unsupported. So I was wondering if there is a way to work around it. I spent hours searching for some fix for it, but could not find anything. I also tried asking reddit on r/Tibia & r/xfce but no one could help me. So I thought trying asking the wizards from Gentoo if you guys know if I can append an icon to an executable file or link it in some way? Is it possible to fix it?


Thank you all in advance.

EDIT: I already created an tibia.desktop file and put it under /usr/share/applications and under .local/share/applications. It worked on whisker menu, but the xfce-panel still does not display the icon when I open the client. Should I copy the icon to another place? Maybe it tries to search for the icon somewhere else?

While there are various ways to do such things, te proper way works different:
You create an .desktop file that links to the icon and the application.
While this article describes how you create an menu entry, the same files can put on your desktop.

I don't know if xfce supporst .ico but you can easily the ico to an png:

hey @wanne32, thank you for your reply.

I forgot to mention, but I already created a .desktop file and copied it to /usr/share/applications and to .local/share/applications. Under whisker menu it worked fine. But when I open the Tibia client the xfce panel still does not display the icon. I'm not using the 'Tibia.ico' file that is provided by Tibia. I'm using the icon provided by Papirus (/usr/share/icons/Papirus/*x*/apps/tibia.svg).

Should I copy the icon to some other directory? The .desktop file that you mentioned above should be copied to another directory?

Other thing I forgot to mention is that I'm not using xfdesktop. I'm using xfwm and everything related to xfce. I already tried install xfdesktop to see if it solved the problem, but it didn't.

Here is what I've installed related to xfce:

From a quick look at 'strace' output, I have a feeling they are not properly using 'QWindow::setIcon()' in the application, referenced by the 'Setting the Application Icon' Qt article [1], as I don't see any attempt to read the icon file from the proper locations... but I may be missing something.

Would also kind of imagine it not working on their supported platform either in that case.
