Thanks, but same result, does it work that way at all?

GLib-GObject-CRITICAL **: 23:22:53.584: g_enum_get_value_by_name: 
assertion 'G_IS_ENUM_CLASS (enum_class)' failed


EnumClass enumc = (EnumClass)typeof(Gdk.WindowState).class_ref ();
var state = (Gdk.WindowState)enumc.get_value_by_name("FOCUSED").value;


I think it is better and easier to use int and string instead of enum

var val = ((int)get_window().get_state()).to_string();
.
var state = (Gdk.WindowState)int.parse(val);

Yes, i also think GtkChild is correct, i just remember that i have a 
similar problem with gtk-sharp.


Found the problem,

I'm kidding, forgot to include the namespace

Everything works fine, thanks a lot!

Not sure if it's the only way, but the following project uses 
 in the UI filethen instantiates the widget in 
the constructor of the main window and adds it to that window.
These files might give you a way to achieve what you want:

It sounds like you are trying to use a widget contained within
another widget?
I would try that in the GtkBuilder file. So the second widget is
references as a component within the larger widget, but is defined
separately. The Vala code would be two separateclasses with the
relevant GtkTemplate annotations.

No there isn't. You either use [GtkChild] in a class marked with 
[GtkTemplate] and
Vala generates the right code for you or you code it all using the 
GTK+ API.
