Plugin Adapter Classes?

[wysota]

Well,the plugin thing is actually kind of difficult for me.According to the QT tutorial I read,plugins have to inherit from an interface,so the QPluginLoader will recognize them.
But if you take a look at QtCreator's source code,you wil find that it doesn't use marcos like Q_EXPORT_PLUGIN2().Besides,all the plugins inherit from a abstract base class called IPlugin(not interface).And the QPluginLoader still loads them.
And I want to know why too...

Please don't cross-post. What you say has nothing to do with the subject. Plus you have already been answered in the other thread so don't continue writing false statements.
