I need a custom tray icon for my application written in python. I am using the code from ubuntu wiki. https://wiki.ubuntu.com/DesktopExperienceTeam/ApplicationIndicators#Python_version
The problem is, I can not create image from file. So I assume I need the name for my icon. Something like Gtk.STOCK_HOME or "indicator-messages". I can't find any documentation how to define the name for my icon in the system.
Any DOCs? For GTK3 Python 2.7 are used in my app.
Finally found a hack:
put the icon in your home directory and run this command.
$ sudo xdg-icon-resource install --novendor --size 16 my-icon.png my-icon-name
Than just run the code from ubuntu wiki.
