[Qt-interest] Extending applications with plugins (QPluginLoader)

[Bastian Bense]

Thanks for the response.
Unfortunately this does not solve the problem of accessing the host
application's objects from the plugin.

How would I conveniently call code/functions in the host application
from the plugin?
