Hi,
I created a plugin mechanism for my application orientating
at the mechanism described by Martin Alchy in
http://martyalchin.com/2008/jan/10/simple-plugin-framework/
Now I'd like to call methods like `initialize(parent)' when
the user chooses to use a plugin. As described in the blog
mentioned above, I only have access to the general type called
`PluginMount' (holding all the actual plugin instances).
I tried to define "abstract" methods in PluginMount type
raising a `NotImplementedError' but it seems, there is no
late binding (similar to Java), so the right method would be
called. Only the message
TypeError: unbound method initialize() must be called
with GeoCache instance as first argument (got PluginMount
instance instead)
`GeoCache' would be the plugin type. What is strange, is the
fact, that when asking what instances are hold by PluginMount
[<class 'geocacheplugin.GeoCache'>]
is listed. So it seems, that no late binding is applied when
calling the `initialize(self, parent)' method.
I'm quite new using Python, so this might be a quite basic
question caused by some misunderstandings in general. Feel
free to point me to appropriate site to solve my problem.
It seems that GeoCache is not a subclass of PluginMount.
