[gtkmvc-users] Communicating between sub-models/sub-controllers

[Steve M. <smc...@gm...>]

Hey list,

This may be a dumb question, but I can't quite find a clear answer.

I am implementing a music player using the gtkmvc framework, where the
parts relevant to this discussion are structured as follows.

I have a set of top level classes, appController, appModel, appView.
Under appController I have a collectionController, and a
playlistController, which each have their own respective view and
model. They represent the music collection in a database, and the
current playlist. I have a signal handler in collectionController
which should add a song to the current playlist. Thus,
collectionController needs to call a method in either
playlistController, or directly on playlistModel (a ListStoreModel).

The only apparent solution I can come up with is to pass a reference
to playlistModel into the constructor for collectionController, but
somehow this seems messy to me. Is there a better way to do this?

I will also encounter a problem with my actual playback code, which I
intend to create as another sub-model of appModel. Will signals
emitted from a sub-model make it to the parent model's controller
without help?

Thanks in advance,

-Steve
