Detailed Description

A Gtk::ShortcutAction that invokes a callback.

Member Typedef Documentation

using Gtk::CallbackAction::SlotShortcut = sigc::slot<bool(Widget&, const Glib::VariantBase&)>

Slot for shortcuts based on user callbacks.

For instance:

void on_shortcut(Widget& widget, const Glib::VariantBase& args);
Parameters
widgetThe widget passed to the activation.
argsThe arguments passed to the activation. Can be empty, if there are no arguments.
