[Rhythmbox-devel] How to import RBIRadioSource reference

[Jannik Heller <scrawl baseoftrash de>]

Hi,

I want to get a reference to the "Radio" source in my plugin. I want to
use this code:

for group in shell.props.sourcelist_model:
      for source in group.iterchildren():
         for props in source:
             if isinstance(props, RBIRadioSource):
                 radio_source = props

However, I get

NameError: global name 'RBIRadioSource' is not defined

So how to import the RBIRadioSource that I can access it? Or does
someone know another way to get the Radio source?
