This got released the same day as my chuck jokes application haha

@Zibri: use Requests instead.

Single Click Functionality using set_secondary_activate_target

Can you tell us how to add the middle click functionality to your code so that it'll take one click on the indicator to see the latest joke?

This functionality is provided by the set_secondary_activate_target() method.

Inserting this line menu.indicator.set_secondary_activate_target(joke) in this section doesn't give errors in the Eclipse IDE:

def build_menu():
    menu = gtk.Menu()
    item_joke = gtk.MenuItem('Joke')
    item_joke.connect('activate', joke)
    menu.indicator.set_secondary_activate_target(joke)
    menu.append(item_joke)
    item_quit = gtk.MenuItem('Quit')
    item_quit.connect('activate', quit)
    menu.append(item_quit)
    menu.show_all()
    return menu

However attempting to run it, it fails with these errors:

Traceback (most recent call last):
  File "/home/users/l/j/ljames/workspace/pythontest/src/test.py", line 55, in <module>
    main()
  File "/home/users/l/j/ljames/workspace/pythontest/src/test.py", line 24, in main
    indicator.set_menu(build_menu())
  File "/home/users/l/j/ljames/workspace/pythontest/src/test.py", line 32, in build_menu
    menu.indicator.set_secondary_activate_target(joke)
AttributeError: 'Menu' object has no attribute 'indicator'

By the way, I removed the version runtime errors by added these lines:

import gi
gi.require_version('Gtk', '3.0')
gi.require_version('AppIndicator3', '0.1')
gi.require_version('Notify', '0.7')

Thanks in advance for any suggestions or comments from anyone!

After constant testing, the following works:

Adding a parameter to the build_menu() function works:

indicator.set_menu(build_menu(indicator))

and

def build_menu(indicator):

Clicking the icon with the middle button will bring up the joke.

This is the new code:
