Poping a tray icon menu on right click and perform a simple action on tray icon left click, works nice with your code.
But when you need to pop a menu on tray icon LEFT mouse click (combination of "activate" and menu.popup ), this becomes a bit tricky,

Using parts of your code and of other people codes, i have made two working examples:
https://github.com/gevasiliou/PythonTests/blob/master/TrayLeftClickMenu.py (combine menu.popup with left click "activate" action)
https://github.com/gevasiliou/PythonTests/blob/master/TrayAllClicksMenu.py (pops up the same menu in both left , right and middle click using "button-press-event")

I'm just posting this info here for future reference of anyone looks similar code to popup the default tray icon menu using any mouse click.

This is python 2 only, right?

I've got this error:
