Retrieve a widget from a gtk::Builder

• Before:

  Example:

  let builder = gtk::Builder::new_frm_resource("/org/gnome/App/ui/widget.ui");
  let widget: gtk::Label = builder.object("my_label").expect("Failed to find my_label object");
  widget.set_text("Hello world!");
  

• After:

  Example 1:

  let builder = gtk::Builder::new_from_resource("/org/gnome/App/ui/widget.ui");
  get_widget!(builder, gtk::Label, my_label);
  my_label.set_text("Hello world!");

  Example 2:

  let builder = gtk::Builder::new_from_resource("/org/gnome/App/ui/widget.ui");
  get_widget!(builder, gtk::Label, @my_label).set_text("Hello world!");
