var label = new Gtk.Label ("Title"); var switcher = new Gtk.Switch ();

switcher.set_active (true);

switcher.notify["active"].connect (switcher_cb);

class MyApplication : Gtk.Application { protected override void activate () {

var window = new MyWindow (this); window.show_all (); //show all the things }

internal MyApplication () { Object (application_id: "org.example.checkbutton"); } }

int main (string[] args) { return new MyApplication ().run (args); }
