Expand description

A helper that impls Signal and its related traits.

Syntax

use glib_signal::{impl_signal, SignalFlags};
impl_signal! { impl Notifies<"signal-name" as SignalType> for AnObject {
    //impl {const SIGNAL_NAME}; // provide a convenient accessor for the default signal handler
    impl BuildSignal; // provide a default impl to facilitate GObject type construction
    FLAGS = SignalFlags::NO_RECURSE; // optionally specify flags for the signal when building
    fn(&self, String) // finally, specify the callback handler signature (with optional return type)
} }
