I've created a UI in glade and I want to use it inside my vala app. I need to derive my own Gtk.Window and

       var window = (MyWindow) builder.get_object("gld_top_window"); // !!!!!! does not work correctly

does not work well for me. Besides I need to pass Gtk.builder reference to MyWindow to be able to handle 
the ui inside my custom window class. In C++ we could do this using get_widget_derived. I didn't see the 
same mechanism in Vala's gtk library. would someone please help me?

Do you have MyWindow in your .ui file?

I do this quite extensively in my application, here is one example:

and the .ui-file:

it was a while since I wrote that and I'm not sure if you need to
explicitly add the Buildable interface or if that comes with the
widget you inherit.. but anyway.. something like that ought to get you
