Hello, I just recently found out that wx.lib.pubsub has finally moved away from wx, and now lives at:
http://pubsub.wiki.sourceforge.net I'm trying to use pubsub3, which is the third version and now the default one, but I'm having a hard time creating topics and messages for sending: class Topic: __init__(self, _name, _description, _parent=None, **kwargs) | Specify the name, description, and parent of | this Topic, and the list of kwargs allowed on listeners | of this topic. The non-kwargs all start with a '_' to | minimize the chance of conflict with a kwargs key. from pubsub import pub class Test(pub.Topic): def __init__(self): pub.Topic.__init__(self, 'Topic.Test', 'This is a test topic') class Msg(pub.Message): pass pub.sendMessage(Test()) Traceback (most recent call last): File "topics.py", line 80, in <module> pub.sendMessage(Test()) File "build/bdist.linux-i686/egg/pubsub/pubsub3.py", line 421, in sendMessage File "build/bdist.linux-i686/egg/pubsub/pubsub3.py", line 195, in sendMessage File "/home/frank/test/topics.py", line 155, in getTopic File "/home/frank/test/topics.py", line 162, in __getTopic TypeError: iteration over non-sequence. pub.sendMessage(Msg()) Traceback (most recent call last): File "topics.py", line 80, in <module> pub.sendMessage(Test()) File "build/bdist.linux-i686/egg/pubsub/pubsub3.py", line 421, in sendMessage File "build/bdist.linux-i686/egg/pubsub/pubsub3.py", line 195, in sendMessage File "/home/frank/test/topics.py", line 155, in getTopic File "/home/frank/test/topics.py", line 162, in __getTopic TypeError: iteration over non-sequence. The variable in question for class Test() contains: Topic 'T.o.p.i.c...T.e.s.t': This is a test topic. Listeners that have 'topic=pub.AUTO_PASS_TOPIC' as a kwarg will get the topic name as value of topic (ie 'T.o.p.i.c...T.e.s.t'). Listeners must otherwise be callable with no args. No listeners are currently subscribed. There are currently no subtopics. which of course is non-iterable. Same for class Msg(), So obviously my Topic and Message class constructors are wrong. The code on the wiki is for pubsub2, and seems to be outdated compared to pubsub3 API. pubsub1 is the same as wx.lib.pubsub btw. Basically I'm looking for example code to get me kickstarted using pubsub3. Best regards, Frank -- http://mail.python.org/mailman/listinfo/python-list
