I use ruby-libappindicator bindings to manage ubuntu application indicators.
I want to indicate if port 3000 is used by any application. Port checking isn't a problem but I also need to update the indicator (I want to show the green or red circle) when port becomes busy/free.
I can create a new indicator like this:
require "ruby-libappindicator"
indicator = AppIndicator::AppIndicator.new("test", "indicator-messages", AppIndicator::Category::APPLICATION_STATUS)
indicator.set_menu(Gtk::Menu.new)
indicator.set_status(AppIndicator::Status::ACTIVE)
Gtk.main
But after Gtk.main call the code "hangs" so I can't call any other method.
How I can update the appindicator icon after its creation?

Use g_timeout_add_seconds() from GLib to define a function that is called at regular intervals and in this function check the port and call
indicator.set_status(...)is needed.
