When you download a new application from the web, you don't have a launcher automaticaly. For instance, you want download the last version of Cura for 3D printing. The downloaded file is a AppImage.
You can directly run this file if you're setting his rights:
chmod a+x Ultimaker_Cura-4.6.1.AppImage
But you can't find yet this executable directly in ubuntu's dock.
To do that, create a
.desktop file in
[Desktop Entry] Version=3.4.1 Name=Cura Comment=Ultimaker Cura 3.4 High-Performance 3D printing software Exec=/usr/local/bin/cura/Ultimaker_Cura-4.6.1.AppImage Icon=/usr/local/bin/cura/cura.png Terminal=false Type=Application Categories=Utility;Application;Development;
Don't forget to change the path of the executable and the path of the icon
Now, you can call your application by the Ubuntu's dock.
