Derive Macro woab::WidgetsFromBuilder

#[derive(WidgetsFromBuilder)]

Represent a set of GTK widgets created by a GTK builder.

This needs to be a struct, where each field is a GTK type and its name must match the id of the widgets in the Glade XML file. This derive implements a From<&gtk::Builder> for the struct.

#[derive(woab::WidgetsFromBuilder)]
struct MyAppWidgets {
    main_window: gtk::ApplicationWindow,
    some_button: gtk::Button,
    some_label: gtk::Label,
}
