Re: [Geary] First collaboration

[Marvin W <gnome larma de>]

Hi José,

Without looking too deep in what you are actually doing: 
gtk_tree_model_get_iter_first is a GTK+ C method, however Geary is 
written in Vala.

Vala is an object-orientated language based on GLib and GObject.
Usually GObject C member methods are realized as object member methods 
in Vala. This means that instead of calling 
gtk_tree_model_get_iter_first(model, iter) you call 
model.get_iter_first(iter), just as in other object-orientated 
programming languages. Sometimes the Vala methods are a little 
different from how it's done in C, but in most cases, guessing works 
fine and in case it does not you can check the valadoc info site [1].

Cheers,
Marvin
