[Vala] connecting signals from GtkBuilder

2012-05-24 Thread D.H. Bahr 
Hello everyone!

I have an issue while trying to connect the signals from GtkBuilder
object to my class' methods. 

This is roughly me code structure:

//No namespace specified

class MyClass {
  ...
  public MyClass () {
builder = new Builder();
builder.add_objects_from_file(builder_file, {"main_window"});
...
builder.connect_signals(this);
  }
  ...
  public void on_signal_emited (signal signature) {
...
//do stuff
...
  }
}

On Glade I connect the signal as follows:
'emit-signal': 'my_class_on_signal_emited'


The code compiles just fine, at runtime I get:
Gtk-WARNING **: Could not find signal handler
'my_class_on_signal_emited'.

How should I name signature handlers on Vala??

Best regards,
