Expand description

Trait containing widget class methods that can be called on any widget type at runtime, without requiring a subclass.

This trait is implemented for glib::Class<T> for any T: IsA<Widget> (e.g., Class<Widget>, Class<TextView>, Class<Button>).

§Example

use gtk::prelude::*;

let class = glib::Class::<gtk::TextView>::from_type(gtk::TextView::static_type()).unwrap();
let trigger = gtk::ShortcutTrigger::parse_string("<Meta>c").unwrap();
let shortcut = gtk::Shortcut::new(Some(trigger), Some(gtk::NamedAction::new("clipboard.copy")));
class.add_shortcut(&shortcut);
