Derive Macro woab::BuilderSignal

#[derive(BuilderSignal)]

Represent a GTK signal that originates from a GTK builder. See the corresponding trait.

Must be used to decorate an enum. Each signal one wants to handle should be a variant of the enum. Unit variants ignore the signal parameters, and tuple variants convert each parameter to its proper GTK type.

#[derive(woab::BuilderSignal)]
enum MyAppSignal {
    SomeButtonClicked, // We don't need the parameter because it's just the button.
    OtherButtonClicked(gtk::Button), // Still just the button but we want it for some reason.
}
