This is NOT for application-indicators but system-indicators.
The objective is to show indicator-sysmonitor in Greeter/Lock/Ubiquity screens. There is a work around in:
C Original Code: (working fine)
I already get one working in C language, see my other question:
indicator-sysmonitoris already developed in Python as many other application indicators. I don't like the idea that developers obliged to port their projects to C or write a Python-C proxy if they want to show the indicator in greeter/lock/ubiquity screens. Instead, making indicator-sysmonitor creates a system indicator directly from python would be the best solution (no workarounds, and it will be a generic solution for all python projects that currently using appindicator).
Python Code: (My failed trial to port c code to python)
I'm struggling to port it into Python. Here is my current code which doesn't work. It does create DBus object for both Menu & Actions. It is listed in the XFCE indicators plugin. But not showed on the panel.
#!/usr/bin/python2 import os import sys import gi from gi.repository import Gio, GLib APPLICATION_ID = 'local.sneetsher.indicator.test' DBUS_MENU_PATH = '/local/sneetsher/indicator/test/desktop' DBUS_ACTION_PATH = '/local/sneetsher/indicator/test' def callback(): print ok def quit_callback(notification, loop): global connection global exported_action_group_id global exported_menu_model_id connection.unexport_action_group (exported_action_group_id) connection.unexport_menu_model (exported_menu_model_id) loop.quit() def cancel (notification, action, data): if action == "cancel": print "Cancel" else: print "That should not have happened (cancel)!" def bus_acquired(bus, name): # menu submenu = Gio.Menu() submenu.append("Show", "show") item = Gio.MenuItem.new(None, "_header") item.set_attribute([("x-canonical-type","s","com.canonical.indicator.root")]) item.set_submenu(submenu) menu = Gio.Menu() menu.append_item (item) actions = Gio.SimpleActionGroup.new() action1 = Gio.SimpleAction.new("_header", None) actions.insert(action1) action2 = Gio.SimpleAction.new('show', None) actions.insert(action2) action2.connect("activate",callback) global connection connection = bus global exported_action_group_id exported_action_group_id = connection.export_action_group(DBUS_ACTION_PATH, actions) global exported_menu_model_id exported_menu_model_id = connection.export_menu_model(DBUS_MENU_PATH, menu) def setup (): #bus connection Gio.bus_own_name(Gio.BusType.SESSION, APPLICATION_ID, 0, bus_acquired, None, None) if __name__ == '__main__': connection = None exported_menu_model_id = 0 exported_action_group_id = 0 password = "" loop = GLib.MainLoop() setup () loop.run()

I expect the reason why, I didn't create the menu structure or its meta (pseudo items like
_header) as they are in the original C code.
Could anyone make a working port of this system indicator code in C to Python?
