我正在试图找出如何使用带有pidgin的dbus

Question

My problem is I'm not sure how to interface them. Do I need to have pidgin installed in a particular way in order for dbus to interface with it? and if not does the pidgin gui have to be running in order for dbus to utilize it?

Answer 1

As per this source you could do the following :

#!/usr/bin/env python

def cb_func(account, rec, message):
    #change message here somehow? 
    print message

import dbus, gobject
from dbus.mainloop.glib import DBusGMainLoop
dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
bus = dbus.SessionBus()

bus.add_signal_receiver(cb_func,
dbus_interface="im.pidgin.purple.PurpleInterface",
signal_name="SendingImMsg")

loop = gobject.MainLoop()
loop.run()

Probably you can get started with this lead.

Answer 2

import dbus
from dbus.mainloop.glib import DBusGMainLoop

main_loop = DBusGMainLoop()
session_bus = dbus.SessionBus(mainloop = main_loop)
obj = session_bus.get_object("im.pidgin.purple.PurpleService", "/im/pidgin/purple/PurpleObject")
purple = dbus.Interface(obj, "im.pidgin.purple.PurpleInterface")

Then you can use the purple object to call some methods like this:

status = purple.PurpleSavedstatusNew("", current)
purple.PurpleSavedstatusSetMessage(status, message)
purple.PurpleSavedstatusActivate(status)

Answer 3

A really useful tool to use when getting started with using DBUS to interface with Pidgin is D-Feet . You can see all the available methods you can call and even execute them directly from the GUI.

Answer 4

The code below has an example of showing the buddy list when it is hidden and another example of starting an IM conversation with a specific contact.

import dbus
BUS_ARGS = ('im.pidgin.purple.PurpleService', '/im/pidgin/purple/PurpleObject')
obj = dbus.SessionBus().get_object(*BUS_ARGS)
purple = dbus.Interface(obj, 'im.pidgin.purple.PurpleInterface')

# show buddy list if it is hidden
purple.PurpleBlistSetVisible(1)

# start IM conversation with specific contact
account = purple.PurpleAccountsFindConnected('', '')
conversation = purple.PurpleConversationNew(1, account, 'alice@example.com')

I can recommend a number of useful resources relating to using dbus with pidgin:

• Riding the D-Bus with Pidgin - Has three separate python dbus examples.
• purple-remote - It's a python script that was installed on my ubuntu machine when I installed pidgin. Its a single file and pretty easy to read through.
• dbus-monitor - Great program to monitor dbus calls. It can help you discover what calls are being used by programs you use when you can't find them documented.
• qdbusviewer - Great graphical tool that can list pidgins dbus methods. You can also call them from the tool itself.

Answer 5

You do not need to do any special configuration of Pidgin to use D-Bus, however it must be running if you want to use it. You can check the script I'm using to control Pidgin status from the NetworkManager-dispatcher ( part 1 , part 2 ) as a sample how to interface Pidgin via D-Bus from python.
