Python indicator

[ukblacknight]

Hi all,

I've been thinking about writing a plugin for emesene so that it integrates into the indicator-applet (https://wiki.ubuntu.com/MessagingMenu/), like pidgin, evolution, gwibber etc etc.

Since emesene is in python, I'd give it a go in python, although I have pretty much no experience in the language!

I followed this article (http://www.gnomejournal.org/article/67/an-introduction-to-the-message-indicator), however it won't run:



Traceback (most recent call last):
File "indicate.py", line 31, in <module>
server = indicate.indicate_server_ref_default()
AttributeError: 'module' object has no attribute 'indicate_server_ref_default'
tom@blacknight:~/Projects/Python$


So I thought I'd inspect the indicate library in python:


>>> import indicate
>>> dir(indicate)
['INTEREST_INDICATOR_COUNT', 'INTEREST_INDICATOR_DISPLAY', 'INTEREST_INDICATOR_SIGNAL', 'INTEREST_NONE', 'INTEREST_SERVER_DISPLAY', 'INTEREST_SERVER_SIGNAL', 'Indicator', 'IndicatorMessage', 'Listener', 'Server', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '_indicate', 'ctypes', 'indicate_listener_ref_default', 'indicate_server_ref_default', 'indicate_server_set_dbus_object', 'indicator_id', 'server_dbus_name']


So, the "indicate_server_ref_default" attribute (I'm sure it should be a method?) does exist. Any ideas why python would imply that it does not?

Below is the code that I have:


import gobject
import gtk
from time import time
import os

try:
import indicate
except:
indicate = None

curdir = os.getcwd()
desktop_file = os.path.join(curdir, "indicate.desktop")

def timeout_cb(indicator):
print "Modifying properties"
indicator.set_property_time("time", time())
return True

def display(indicator):
print "Ah, my indicator has been displayed"
indicator.hide()

def server_display(server):
print "Ah, my server has been displayed"

print __name__

if __name__ == "__main__":

# Setup the server
server = indicate.indicate_server_ref_default()
server.set_type("message.im")
server.set_desktop_file(desktop_file)
server.connect("server-display", server_display)
server.show()

# Setup the message
indicator = indicate.IndicatorMessage()
indicator.set_property("subtype", "im")
indicator.set_property("sender", "Test message")
indicator.set_property("body", "Test message body")
indicator.set_property_time("time", time())
indicator.show()
indicator.connect("user-display", display)

# Loop
gobject.timeout_add_seconds(5, timeout_cb, indicator)
gtk.main()



Note: The try: except: statement is something I noticed in the source code for gwibber - I tried that to see if it had any effect.

youre using indicator rather than indicate

should be indicate.indicate_server_ref_default

otherwise youre essentially trying to use
indicate.IndicatorMessage().indicate_server_ref_de fault

It is indicate.indicate_server_ref_default, the problem is on line 31:


server = indicate.indicate_server_ref_default()

[benj1]

yes youre correct, my appologies.

im not sure ive never used the module before, it seems correct, certainly your listing of the module seems to suggest its correct. what happens when you get rid of the try except block at the start, at the moment its just hiding any potential import errors you may have, im guessing the problem will lie there, rather than with the function

[ukblacknight]

Exactly the same problem. When I aasked a friend to inspect the indicate library on his ubuntu box, his results differed to mine, and indicate_server_ref_default wasn't listed. Could you, or someone else try it on their machine?

[benj1]

just tested it, works fine for me, im using python 2.6 and standard python-indicate from the repos.

By 'it', do you mean the entire script?

I just tested it, I got the error at first, and then I didn't, and I don't know why. Changing indacate.IndicatorMessage() to indicate.Indicator() on line 38 got rid of all errors.

Tried that, problem still persists :\

I tried inspecting the indicate library again, and now the results are different!!


>>> import indicate
indicate
>>> dir(indicate)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', 'curdir', 'desktop_file', 'display', 'gobject', 'gtk', 'indicate', 'os', 'server_display', 'time', 'timeout_cb']
>>>

[benj1]

full script and that function both fine.

whats the contents of the library ?
it'll be in /usr/lib/python2.x/dist-packages

If you mean what I think you mean, then this is the result:


tom@blacknight:/usr/lib/python2.6/dist-packages/indicate$ ls -lh

lrwxrwxrwx 1 root root 41 2009-08-29 11:07 _indicate.la -> /usr/share/pyshared/indicate/_indicate.la

i was thinking more the contents of your files, your last listing seemed to show all of your functions which i dont think should happen, i just want to make sure all the links etc are ok.

have you tried reinstalling the library ?

[unutbu]

ukblacknight, did you put your own personal code in a file called "indicate.py"?
If so, when you run your personal version of indicate.py, python thinks you've replaced the standard indicate module with your own.

If my guess is correct, then the solution is to rename your file something (anything!) that doesn't conflict with a standard library module name.

[ukblacknight]

I reinstalled the library, no changes :(

BOOM! Done :D I had actually renamed the file much earlier on, to "example-indicate.py", but the "indicator.pyc" and "indicator.py~" files were still there. I just deleted them, and now it works!

Thanks :)
